Night Moves(1975)

Maybe he would find the girl... maybe he would find himself.

Private detective and former football player Harry Moseby gets hired on to what seems a standard missing person case - a former Hollywood actress wants Moseby to find and return her daughter. Harry travels to Florida to find her, but he begins to see a connection between the runaway girl, the world of Hollywood stuntmen, and a suspicious mechanic when an unsolved murder comes to light.
