It's 1963, and Chief Riley Bennett knocks on Dody Canfield's door informing her that her husband died instantly when his car struck a telephone pole. Not wanting to raise her three children alone, it isn't long before she brings home Frank Billings; and he's moving in. Mama sends thirteen-year-old Missy to take her little brother, Billie, fishing so she can have some alone time with Uncle Frank. Billie casts his line into the murky river water hooking the big one; granddaddy of all fish. He quickly hands the reel to Missy hoping not to lose his catch. Missy reels in slowly--bubbles begin emerging--releasing an undercurrent of secrets, deadly lies, and terror on the Canfield family.
