Unfortunately, the pristine image she's created becomes dismantled when everyone finds out that her marriage to Pat is ending. Actress Martha Plimpton is known for her work on the TV series, Raising Hope. She has also appeared on The Good Wife, Law & Order: SVU, Fringe, and How to Make It In America. (Getty)
