TEXT: OPENING CREDITS Holding a red folder, Donna walks along a crowded street. The Doctor walks on another crowded street. Donna looks up to a high building, then walks toward it. The Doctor looks up to the same building from the other side. Donna enters through the main entrance. EMPLOYEE (voice-over): Good morning, Adipose Industries. The Doctor opens a fire exit with the sonic screwdriver and enters the building. Donna flashes a card to the security guard. DONNA: Donna Noble, Health and Safety. The Doctor walks on a deserted corridor. He flashes the psychic paper to the security guard. DOCTOR: John Smith, Health and Safety. About three dozen people, including Donna, are sitting in a lecture room listening to Miss Foster. MISS FOSTER: Adipose Industries. The 21st century way to lose weight. No exercise, no diet, no pain. Just lifelong freedom from fat. The Holy Grail of the modern age. And here it is. You just take one capsule, one capsule, once a day, for three weeks. And the fat, as they say... COMPUTER VOICE: The fat just walks away. PENNY: Excuse me, Miss Foster, if I could? I'm Penny Carter, science correspondent for The Observer. There are a thousand diet pills on the market, a thousand con men stealing people's money. How do we know the fat isn't going straight into your bank account? MISS FOSTER: Oh Penny, if cynicism burnt up calories, we'd all be as thin as rakes. But if you want the science, I oblige. COMPUTER VOICE: Adipose Industries. The Adipose capsule is composed of a synthesised mobilising lipase, bound to a large protein molecule. The Doctor is watching the demonstration from the projector room. COMPUTER VOICE (through the window): The mobilising lipase breaks up the trigycerides stored in the adipose cells, which then enter... The Doctor shows the psychic paper to the man handling the project
SUMMARY:
Donna Noble finds herself regretting declining the Doctor's invitation to travel in the TARDIS, and investigates conspiracy theories in the hope that she will find him again. The Doctor and Donna, neither aware of the other's involvement, both investigate Adipose Industries, which is marketing a special diet pill . The pills use body fat to parthenogenetically create small white aliens called Adipose. The Doctor and Donna separately infiltrate Adipose Industries. As they explore the building, they encounter each other through opposite windows in an office. They are confronted by Miss Foster, an alien who is using Britain's population to create Adipose babies. The Doctor creates a diversion and escapes, so Miss Foster accelerates her plans. Throughout London, the Adipose begin to spawn and soon number several thousand. The Doctor and Donna prevent the plan from killing those who had taken the pill, and the remainder of the young Adipose make their way to Adipose Industries. The Adiposian First Family arrive in a spaceship and collect their young. The Doctor refrains from killing the young Adipose because they are children, to which Donna remarks that Martha Jones made him more human. Donna accepts the Doctor's offer to travel in the TARDIS.
