Charlie Chan at the Olympics

Charlie Chan at the Olympics is a 1937 American mystery film directed by H. Bruce Humberstone and starring Warner Oland, Katherine DeMille and Pauline Moore.

Charlie Chan is proud of his oldest son, swimmer Lee (Keye Luke), being chosen to represent the United States at the 1936 Summer Olympics in Berlin.

On the passenger list of the only aircraft to leave Honolulu for the mainland after the incident are Richard Masters (Allan Lane) and Yvonne Roland (Katherine DeMille).

Perusing the list, Hopkins (Jonathan Hale) recognizes the name of arms dealer Arthur Hughes (C. Henry Gordon).

When the ship docks, German Inspector Strasser, Chan, and Hopkins go to question Roland, only to find her gone and her cabin rifled.

Hughes advises Chan to stop investigating, then spots a gun barrel in a passing car and pushes the pair to safety.

Roland takes the candy box to her employer, diplomat the Honorable Charles Zaraka (Morgan Wallace).

Hughes threatens to kill Lee if Chan does not produce the real equipment, but the police arrive just in time to rescue the detective.
