TV serien #4

In "Hemmeligheten under vannet," a forgotten German submarine off Long Island hides documents that could unravel the secret past of a respected city official—once a spy during World War II. When divers Steve Randall and Jim Collins are imprisoned for defying orders to stay away from the wreck, their children, Billy and Cindy, take matters into their own hands, diving into a mystery far deeper than they expected.
