Mary and Charlie’s marriage was on shaky ground—he forgot their anniversary, and she nearly had an affair with their friend Trevor, whose wife, Susan, a lawyer, is always working. Mary grows suspicious when Charlie claims he’s working late on a renovation project, so she shows up unannounced, only to find him dead. As police investigate, Charlie’s sister Crystal suspects Mary’s involvement, forcing Mary to seek legal help from Susan.
