Detective Sergeant Tommy Murphy is a maverick cop with a dark past. After failing a psychiatric assessment, he's given one last chance by his boss and given a dangerous undercover assignment. A loner with little to lose and dealing with everything on his own terms, this time around, however, Murphy has an ally in Detective Inspector Annie Guthrie.
