In Common Law, Travis Marks (Ealy) and Wes Mitchell (Kole) have a problem - each other. Despite their differences, this odd couple set of detectives are incredible at what they love most - enforcing the law - and have a seven-year track record as the LAPD's finest in the Robbery-Homicide Division. But when their constant bickering begins to have a major impact on their caseload, their new-age captain (McGee) institutes mandatory couples' therapy to bring back the flame in their "work marriage." Tough-as-nails therapist Dr. Ryan (Walger) is brought in to help them understand and resolve their conflicts and confront their demons in order to enhance their ability to continue solving crimes.
