In a failed attempt to catch "The Cartwheel Killer," Marvin is eager for a new partner who won't slow him down. Someone sleek and tough, with the mustache befitting its own 80s TV show, Marvin looks for a partner just like him, if not better.

During the town's talent show, a serial killer targets the winner as Marvin finds himself at the judging table to capture them in the act.

On a day where murder seems to be on the low, the biggest of Marvin's problems is his missing danish. The quest for the sweet boysenberry danish leads to an explosive case no one saw coming.
