In 1930s Berlin, homosexual Max (Clive Owen) sleeps with German officer Wolf (Nikolaj Waldau), only to see him killed by his fellow Nazis the next morning. Fleeing with his boyfriend, Rudy (Brian Webber), Max is eventually caught and forced to beat his partner to death on a train to prove they have no connection. He's then sent to Dachau concentration camp and meets Horst (Lothaire Bluteau), a proud gay man also bound for the camp. Despite their harsh surroundings, the two fall in love.
