A fired-up Donald Trump is back with a fourth group of 18 entrepreneurial wannabes. Their first task: work up and promote a new fitness class for Bally's Gym. But first, they convene at Trump's golf club in Bedminster, N.J., where the Donald divides them into teams---by gender (the men form Excel Corp., while the women call themselves Capital Edge). Then it's a race---literally---back to Manhattan. The winner gets to choose between two prospective Bally locations.

The task involves an ad campaign for a luxury sports car, and before candidate No. 2 is fired, one will suffer a family loss and another will be injured.

This high-tech task involves exhibitions aimed at senior citizens. Candidate No. 3 is fired after a boardroom session that features a nasty surprise by the project manager.

Trump wannabes scream at each other as Excel and Capital Edge promote a new ice-cream drink. And in the boardroom, candidate No. 4 is iced.

The task: design a parade float to promote an upcoming sci-fi movie. In the boardroom, candidate No. 5 is fired.

The sporting-goods business is spotlighted. In the boardroom, candidate No. 6 is fired.

The candidates become teachers. The losers, of course, get board-room detention, and Candidate 7 must don the dunce cap.

The task: promote the DVD release of "Star Wars: Revenge of the Sith" and a "Star Wars" video game. Eight candidates remain.

The remaining six candidates try to get in tune with the task when they're challenged to write and produce a song for satellite radio.
