Kurt Russell in HAWAII FIVE-O, Deadly Doubles (1977)

When a Soviet tennis team visits Hawaii, a young female star decides to defect in order to be with her American boyfriend. What she doesn’t know is that just before she made a break for it, one of her teammates brained a KGB man with a wrench over a diamond-smuggling operation, and now both she and her boyfriend are patsies in the murder and face far sterner justice than Hawaii can offer if they are captured.
