Clara Colby hopes life has finally settled down. But when the shelter crew is called to help with a cat-hoarding rescue, Clara is plunged into the most dangerous investigation of her life.

As the team races to save dozens of neglected cats, tensions erupt between shelter board member Roberta Osborn and the local animal control director. Hours later, Clara discovers the man dead—stabbed in the heart—leaving Roberta as the prime suspect.

Immediately after discovering the body, Clara spots a mysterious figure fleeing the crime scene and gives chase. The pursuit ends in a crash that nearly kills her. 

While Clara recovers from her injuries and Roberta remains behind bars, a manipulative newcomer gains influence at the shelter, and everything Clara worked to build is slipping through her fingers.

Determined to prove Roberta's innocence, Clara struggles to get to the truth—but the more she investigates, the greater the danger becomes. Because this time, she isn't just investigating a crime—she is the target.
