Shack Twala gets released from prison after 10 years for nationalist activities, but he's on the run following a run-in with the police. With the help of his lawyer Rina Van Niekirk and British engineer Jim Keogh, he flies to Capetown to recover gems he entrusted to a dentist before his imprisonment. Major Horn of the South African State Security Bureau follows them and doesn't arrest them until they reach their goal.
