In return for arranging an escape, the diplomat must turn over to Foster a diary revealing the true events taking place in China. While making his escape, the defector is killed ant the diary vanishes. The reporter sets off on a search for it, from Hong Kong to Australia. The chase ends in an action-filled climax, with the journalist finally meeting up with "That Lady from Peking" (Nancy Kwan) - the diplomat's daughter.
