Former police detective-turned-attorney McBride is called to an L.A neighbourhood after police receive a mysterious emergency call. Tom Mitchell and his wife Sue lie bleeding and unconscious in their kitchen. Tom, a Marine medic who served in Afghanistan, made the 911 call before he blacked out. But there are no immediate signs of an intruder, making Tom, whose injuries aren't as severe as his wife's, a possible suspect. (Hallmark Channel)
