A cupcake rival tries to steal their business! What will Lauren, Annie, and Zoe do?

What happens when a rival sets up his cupcake truck right outside the Norwegian Forest Cat Cafe?

Everyone in the small town in Northern California seems drawn to Jason, the good-looking yet arrogant cupcake baker, and his French Bulldog—which means no customers for the trio.

But when they discover Jason's dead body and are treated as major suspects, they decide to investigate! Who is the killer? The ex-girlfriend? The victim's best friend? Even Ms. Tobin is considered a suspect by the new detective in charge of the case.

Lauren and Mitch go on a double date with Zoe and Chris, while Annie finds a possible clue.

Meanwhile, Zoe's idea for AJ, the kitten Annie found, to train as Annie's assistant in the café, doesn't quite work out as planned.

But when the killer comes knocking, can Lauren, Annie, and Zoe find a way to escape? Or will they have served their last cupcake?
