Journalist buddies Jimmie Daniels and Buzz Nelson have decided to spend their vacation together at the Latonia horse race track on Yucatán, Mexico.

Their plans are seemingly spoiled when their publisher Kingsley orders Jimmie, who is the newspaper's most prominent reporter, to do a story on missing banker Martin James, who stole one million dollars from his bank before disappearing.

But Jimmie finds out about the plan from Kingsley's secretary, Elizabeth Stiles, and tries to intercept Kingley, flying home with Buzz and then sneaking onto the ship he was supposed to arrive on.

When the woman leaves, Jimmie follows her and later contemplates alerting the police, when he hears a radio broadcast announcing himself and a female accomplice as suspected murderers.

The brand new Mrs. De Borest becomes suspicious and opens up the trunk her husband has, finding out from the contents that he is a traveling salesman and not a count as he has led her to believe.

Buzz has picked up Jimmie's trail and arrives at the building, lures his way in and then manage to release everyone locked into the refrigerator room.
