Dan Roman is a veteran pilot haunted by a tragic past. Now relegated to second-in-command cockpit assignments he finds himself on a routine Honolulu-to-San Francisco flight - one that takes a terrifying suspense-building turn when disaster strikes high above the Pacific Ocean at the point of no return.

A San Francisco hood is rubbed out by rival Bruno Felkin, who himself reports the crime to Homicide Lt. Kelsey in an alibi scheme which fails. To escape, he stows away on a fishing boat. At sea, skipper Hamil Linder receives Bruno kindly, teaching him fishing; Bruno enlists Hamil's wayward son Carl to tend his slot machines. Then Carl takes an interest in Bruno's girl Connie. Climax in a storm at sea.
