In 1943, the U.S. Navy abruptly─and quietly─decommissioned and sealed the submarine USS Lionfish. Eighty years later, an academic (Tim Abell) whose fixation with the story cost him his reputation and job is granted the opportunity to board the sub and investigate. The answers that he's so long sought, though, may have an unholy explanation. Maritime menace and mystery with Tom Stedham, Naomi Brockwell, Cambridge Jones. 122 min.
