Ricky Jones is looking forward to his first day on the job as a deputy sheriff in the cougar-run town of Yuma Town, but he doesn’t expect to run into his former girlfriend while he’s wearing his cougar coat. Now he wants her back in the worst way, but he’s sure she’s going to be even madder at him for dumping her three years back.

Mandy Richards is on her way to an interview at a hospital north of Yuma Town for the position of a Licensed Practical Nurse when she hits a cougar in the thick foggy night, a full moon silhouetted in the gloom on Friday, the thirteenth. Checking on the wounded cougar changes her world forever.

But her most recent ex-boyfriend isn’t going along with Ricky’s plans to renew his relationship and things are bound to turn deadly.
