A cop comes to Jillian Sullivan's door with a photograph

The man in the photograph appears to be Rob Sullivan, Jillian's husband, who died four years ago. But the picture was taken after his death and shows him with another woman and a child.

Jillian can't believe her husband could have deceived her in this way. The cop, Adam Ramsey of the LAPD, believes that's exactly what he did.

They both have compelling reasons for wanting to discover the truth. But it means they have to work together, and in the course of doing that, they discover truths about themselves and each other.
