Private Investigator Eddie Valetik, played by Eddie Cibrian is forced to let actress Sam Swift, played by Rachel Bilson, shadow him for one week. However, he learns she is more of an asset than a liability. 

They immediately get a case, a father looking for his missing daughter. The case turns out to be a lot more than they bargained for, when they discover everything they were told is a lie. Sam and Eddie find themselves at a crossroad, to continue or stay out of it. The power players involved want the later putting both of their lives in jeopardy. 

When Sam finds evidence that helps solve the case, she proves to Eddie she learned a thing or two playing a detective on TV for eight years. While Eddie shows there is a lot more to him then meets the eye, including the case that has haunted him for years?

Despite their dislike of each other Sam and Eddie in the end, they do solve the case putting the bad guys away. Their time together has a profound effect on each of them. She realizes there could be more to life than acting and Hollywood. He realizes it might be time to let go of the past.

The publicity from the case has his PI firm flooded with new clients, but the clients are not looking to hire only Eddie. He makes a call to Sam as a new partnership and friendship are born.
