Cassidy Foster is heartbroken, stuck in life, and getting a little too obsessed with plants. Then when a well-connected friend becomes sick of Cassidy's moping and gets her a gig with famous Hollywood couple, Marisol and Nate Sterling, Cassidy jumps at the chance to move to sunny L.A.

The Sterlings are warm and welcoming. A perfect couple. All Cassidy has to do is be available a few hours a week for errands. In return, she has access to luxury. Designer clothes. A sparkling pool. Great pay. When Nate takes interest in her, asking her to read scripts he's written, Cassidy thinks this could be the key to kickstarting her writing dreams. As their business relationship grows, so does their attraction. Nate is sexy, talented, and Cassidy can't believe her luck.

Clearly, Marisol doesn't know what she has. Maybe that's why the two are always fighting when they think Cassidy isn't around. But Cassidy learns she was hired for a different purpose. The Sterlings aren't the perfect couple. Marisol isn't the perfect wife. And when one of them is found dead, Cassidy becomes the perfect suspect.
