Hannibal Brooks (Oliver Reed) is a British prisoner of war assigned to care for an elephant in a zoo in Munich. Along with an American (Michael J. Pollard) and an Austrian (Helmut Lohner), the trio escapes with the elephant and heads for the Swiss border. They use the elephant to tear down a sentry post and gain access to the border crossing. They are betrayed by a Polish girl who aligns herself with the Nazis as the trio of escapees and their pachyderm protector evade the enemy in their attempt to escape. Comical moments are provided by the animal and James Donald who plays a captured British Army chaplain in this World War II adventure feature.
