Mahogany and Rust investigate the mysterious disappearances near Dr Schafer's top secret medical research lab. When the questioning goes awry, Mahogany is injected with a lethal serum, giving him 24 hours to live. Will Rust help? No, he's more interested in Gail, the lab assistant.

The world's greatest art thief, Frenchman Gerard Cliche, is in town. Meanwhile, Mahogany and Rust are out to win the Golden Doughnut, the prize for the best crime-fighting duo. It's surely in the bag too, providing Romero and Byrne don't turn up.

Rust's identical twin brother Vince escapes from Justice City penitentiary with a devious plan to swap places with Rust and infiltrate JCPD. Meanwhile, it's Mahogany's birthday and he's fed up that Rust has forgotten all about it AGAIN. Just typical.
