In finale news, "In Plain Sight" airs its final episode ever on Friday on USA, which sees Mary caught between her "model" witness and an unexpected family reunion. And "Gcb" also ends its first season on Sunday on ABC.
The rest of weekend also offers a few reasons to stay home on the couch. On Saturday, it's SyFy's one night only movie event with "Treasure Island." The new spin on the classic tale features an all-star cast led by Eddie Izzard, Elijah Wood and Donald Sutherland.
