Wallace and Gromit are to return in a half-hour television adventure - the first since 1995's A Close Shave.
Aardman Animations has announced that the cheese-loving inventor and his loyal dog will star in Trouble At' Mill - to screen on BBC One in late 2008.
Creator Nick Park said: "The story takes Wallace and Gromit in a direction we haven't seen before - both emotionally and technically."
Shooting starts in January at Aardman studios in Bristol.
Trouble At' Mill is a murder mystery that sees Wallace and Gromit running a bakery business - with their house converted into a granary with ovens and robotic kneading arms.
It also introduces a new love interest for Wallace - bread enthusiast Piella Bakewell.
The new film will reunite Nick Park with writer Bob Baker who co-wrote both The Wrong Trousers and A Close Shave.
It is the first outing for Wallace and Gromit since The Curse of the Were-Rabbit, which won the Oscar for best animated feature in 2006.
Mr Park said he was looking forward to making a short film after the pressure of a Hollywood feature.
"I love making films for the cinema but the production of Chicken Run and Curse of the Were-Rabbit were virtually back to back and each film took five years to complete," he said.
"This one we're making for the BBC. It's going to be a seven or eight-month shoot. That's faster than we've ever done it before," he told the BBC News website.
"It's nice to be out of that feature film pressure now. I don't feel like I'm making a film for a kid in some suburb of America - and being told they're not going to understand a joke, or a northern saying.
"I'm making this for myself again and the people who love Wallace and Gromit."
