Catherine Black is a brilliant, ruthless businesswoman who runs a top hedge fund in L.A. But below her fabulous, feminine ice-cold public facade, she is privately -- and proudly -- a murderous psychopath. Enter Tyler Jones, a handsome young conman who turns up at Catherine's Malibu mansion by a too-good-to-be-true listing for a "room for rent." Unfortunately, Tyler is unaware he's about to turn out to be her next victim. After being roofied and romanced by Catherine and her slinky model girlfriend, Tyler is swept up in his new life of riches and romance -- blissfully ignorant that in between her board meetings and spin classes, Catherine partakes in serial murders and gruesome dismemberments. But sex and a stolen vintage Mustang (with a corpse crammed in the trunk) complicate their mutual scheming. And when Tyler discovers of a freezer full of body parts in her garage, Catherine uses everything -- including a broken martini glass, a hedge trimmer, a crossbow, and a chainsaw -- to break up and chop up Tyler. All while struggling to keep his blood and her Bordeaux off the custom-made white couches. So, will the Guy get the Girl or will the Girl gut the Guy?
