Plot
Jane Hoyt arrives in Hong Kong, looking for her husband, reckless photojournalist Louis. He entered Communist China without a visa and was imprisoned as a suspected spy. She sees Hong Kong Marine Police Inspector Merryweather, who found Hoyt’s cameras on the junk that took him into China. He can offer little help. During their conversation, he mentions American expatriate Hank Lee, a big name in smuggling and other shady activities.
She decides to arrange his escape, so she contacts Hank. He advises her to give up the foolhardy venture, but she refuses. She foolishly meets Fernand Rocha alone and gives him a $500 deposit to set up a rescue, but he merely gambles the money away and locks her up for his lecherous purposes. Word reaches Hank in time to save her.
Having fallen in love with Jane and realising that she will not let herself get involved with him while her husband’s fate remains uncertain, Hank decides to rescue the man himself. Inspector Merryweather is inspecting Hank’s boat when Hank decides to make his attempt, and is shanghaied into helping rescue the husband, who is being held in prison in Canton.
Louis is freed. Merryweather is forced to help Hank fight off a pursuing Chinese gunboat with a 20mm Oerlikon cannon concealed belowdecks. When they return safely to Hong Kong, Louis graciously bows out of his wife’s life, allowing Hank and Jane to get together.
