Cold Moon takes place in tiny Babylon, Fla., where the granddaughter of Clark’s character is murdered by a mysterious assailant, her body sunk into the black waters of the Styx River — the river where her parents disappeared from their boat a decade earlier. Suspicion falls on a duplicitous banker and his wealthy father, played by Stewart and Lloyd.

Trivia, insights & behind the scenes
