Michelle (GLU014-1) and her friend Jewel (GLU014-4) start growing inside a shop until they unload their energy. The two find new clothes and Michelle goes online to try and find about the growth symptoms. Michelle starts growing again and bursts out of her clothes. Jewel tries to finish searching online about the growth symptoms but she grows as well and they both climax, unloading their energy again.

Private Heidi (GLU014-11) and Private Robert (GLU014-11) arrive at Michelle's house and finds the two ladies passed out. Robert notes that at least they discharged when no one was nearby and they agree to take Jewel (GLU014-4) and Michelle back to the labs on base. Robert watches over Jewel in the back of the truck while Heidi drives with Michelle sitting next to her. Robert notes that Jewel's breasts are at least a size J-Cup or larger as she sleeps on the floor and Robert begins growing. Jewel's breasts start growing as she sleeps and then she wakes up and starts seducing Robert. In the front of the truck Michelle, who is wearing Robert's jacket, begins to wake up next to Heidi who asks if she is ok. Michelle starts growing, bursting out of Robert's Jacket while Heidi grows too. All four of them unload their energy destroying the truck.

The four of them make it to an airport and get on Flight 657. Michelle (GLU014-1) is worried but Jewel (GLU014-4) assures her that Private Heidi (GLU014-11) says its safe as long as they sit separate. On the plane Michelle and Jewel are sitting on either side of Bruce Banner (The Hulk) in one row with Michelle being next to the window. In front of them Private Robert (GLU014-11) is sitting next to Anna Marie (Rogue), and in front of them Heidi is sitting next to Rudy Jones (Parasite). Jewel leans over Bruce to looks outside the window and comments on his muscles and Bruce worries that he is hulking out which would be dangerous on the plane. Rudy is resisting the urge to absorb energy but he does absorb some and grows slightly justifying to himself that he is helping to prevent disaster on the plane from a growth outbreak. Bruce notices that Jewel's breasts are larger, Rudy continues absorbing energy, and Heidi swoons after Rudy in his swollen, muscled state, not even recognizing that he is the same person. Heidi gives in to the growth, inhaling and making her breast bursting out of her buttoned-down top. Robert asks Heidi if she is ok as Rogue starts growing. Rudy gives in and also inhales absorbing the energy from Heidi, shrinking her and then growing so large his head hits the ceiling of the plane cabin. Jewel give into the growth and tries to bust her remaining overall strap off. Rogue continues to grow as Robert starts to feel the affects as well and Jewel's breasts begin to overflow into neighboring seats and rows. Bruce is getting pushed to the side by Jewel's growing breasts when Michelle suddenly starts growing as well, exploding out of her top and wedging Bruce in between her breasts and Jewels. Bruce is unable to hold himself back and starts to grow into The Hulk. Heidi starts growing again and is alarmed by Rudy's grown form as The Parasite. Rogue who is growing behind Rudy senses Rudy is an energy absorbing being like her and Rudy also notices Rogue, both wondering who the other is.

At the front of the plane the pilot and co-pilot both grow out of their clothes and the captain starts having sex with the co-pilot but she worries if they grow too big that they'll destroy the plane. Rudy Jones (Parasite) is still growing and Anna Marie (Rogue) offers to siphon some energy off of him. One of the airplane stewardesses who has already grown out of her clothes radios asking if anyone knows how to a fly a plane since the pilots are currently indisposed. Sofia (GLU014-32) volunteers and is surprised to see various people having sex as she heads up front. Settling into the cockpit Sofia talks over a headset to the control tower who provides instructions but Sofia starts to grow out of her clothes. Sofia heads back to the passenger section to ask for a personal decom to siphon some of her size so she can land the plane. Will (GLU014-36) and his girlfriend Karen (GLU014-36) flag down Sofia and demand an explanation for the state of the flight. Will immediately grows when next to Sofia and Sofia asks him to have to sex with her and he agrees.

Private Robert (GLU014-11) has not yet grown and is still sitting next to Anna Marie (Rogue). Robert starts to feel the effects and his penis violently bursts out of his pants and he grows out of his clothes. Robert grabs onto Rogue and the two start having sex. Sofia (GLU014-32) and Will (GLU014-36) finish having sex and return to normal size. Sofia gets back in the pilot seat with Will sitting next to her as co-pilot. Will and Sofia start to grow again while bickering but Sofia is able to land the plane successfully. After landing Sofia and Will go back to having sex in their grown state and Sophia begins to give oral sex to Will.

Karen (GLU014-36) walks in and is surprised to find Sofia (GLU014-32) and Will (GLU014-36) having sex. Karen breaks down in distress over the fact that Will broke the promise between them to stay celibate until marriage. In her distress Karen states that she was resisting the growth but no longer will and she grows to a modest size, although she is disappointed that her underwear is still on. Sofia laughs at Karen's attempt to grow, and continues to give a hand job to Will telling Karen she'll “finish [Will] off” for her. Karen is infuriated and puts all of her willpower into growing, her underwear snapping off immediately. Karen's breasts grow disproportionately large to the rest of her body until each breast is three times the size and mass of her already large form. Karen's nipples enlarge and engorge and Karen orders Sofia to finish Will off. Sofia obeys the order as if under hypnosis calling Karen her “mistress” and proceeds to deep throat Will's cock which is now nearly as large as her own head. Karen's breasts continue to grow while her body stays the same size, with energy fluid spurting out of her erect nipples while she laughs maniacally. Sofia manages to deep throat Will's cock all the way to the base, causing his cock to come out the other side of her since the cock is at least twice the length of Karen's torso. Karen is essentially impaled on the phallus, her mouth and body stretching obscenely around it. Will warns Sofia that he is about to cum and Karen encourage him to do so. Will attempts to tell Sofia to get off of his cock before he blows and Sofia tries to move back off of Will's cock as he tries to hold back the buildup of energy. Sofia makes it to the end of Will's cock but it is still inside of her mouth and Will unloads inside of her, causing Sophia's body to expand and inflate like a balloon, excess energy bursting out the other side of her, as Karen continues to laugh maniacally. Afterwards, Will and Sofia are both extremely exhausted but unharmed laying on the floor. Karen stands over Sophia gloating that Sofia deserved what she got. Karen is immediately beamed aboard the Luxembourg and greeted by Luna Masters.

Luna Masters beams Karen (GL14-36) from the airplane to the Luxembourg and informs her that she is a superbattery. Luna determines that Karen's trigger was distress from seeing her boyfriend Will (GL14-36) cheat on her. Replaying the footage causes Karen (GL14-36) to grow again and Luna sees that Karen's data is identical to her own. Alexander Dunn interrupts to inform Luna that Roger Benton and Mika Furihara have escaped and are loose on the Luxembourg. Luna calls for the sealing of the Prison Level and for all personnel to be placed in a detox suit and assemble in the Main Hall. The Decom Level is raised progressively to Level 40 during which Benton and Mika grow out of their detox suits.

Luna activates a room-wide decom then challenges Private Wilson to see who grows out of their clothes first.

Private Wilson grabs hold of Luna, allowing her energy to back up and causing her to start unleashing growth energy on the Luxembourg crew. Luna's voice over the intercom begins hypnotizing those who hear it into growing, including Anne Furihara.

Marsha Robbins arrives on the Luxembourg and uses an advanced decom suit to decom a large portion of the Luxembourg crew but is unable to fully decom Luna before the suit overloads. She finds Alexander Dunn and they both get into Decom Mech Suits and successfully decom Luna and Private Wilson.

Senator Robbins orders Alexander to ride in the tram with Luna as they travel to the landing bay of the Luxembourg. Luna attempts to prove to Alexander that she was in control during the earlier outbreak by having him replicate the position Private Wilson had put her in.

Luna has a dream about giving a valedictorian speech at her college graduation. The crowd heckles her about her large breasts and as she continues in her speech she slowly realizes that she is growing out of her clothes.

Luna and Alexander continue to grow until Senator Robbins arrives and decoms them both.

Luna, Hannah and Alexander are sent off the Luxembourg in a Shuttle to investigate a Growth Lab in China called the Mainland Republic Research Facility. The team attempts to do a demonstration by making Alexander grow but he goes berserk and breaks into the serum holding tanks and drinks the solution, causing the tour guide and Luna to grow.
