Can a couple of baristas chase down a car thief without spilling a drop of their favorite drink? Plans for a Valentine's Day grand opening of a small town coffee shop go awry when the first customer is killed. Evidence points toward the victim being mixed up in a car theft ring, but shop owners Tandy and Marissa have reason to believe he was framed. An assortment of suspects--from a pink-haired heir to Tandy's charming ex--all seem to know a little too much about grand theft auto. Without approval from either their boyfriends or the gum-chewing FBI agent in charge, the shop owners go on stakeouts, plan stings, and pursue justice in a high-speed car chase. If they don't find the killer soon, it might be more than their love lives in trouble.
