Berlin in the 1930ies: the Nazi party's program of genocide against any and all perceived "enemies" is coming into full swing when the party begins a violent purge of homosexuals in its membership. Max, a bisexual playboy, is attending an orgy thrown by drag queen "Greta" and featuring a number of party members when the festivities are raided by the police; Max and his lover Rudy escape, but they are later arrested and sentenced to a concentration camp. En route to the camp, Max betrays Rudy and arranges to get a yellow identification star, marking him as a Jew, instead of a pink triangle, which would signify him as gay; while the Jews are destined to be executed, gay prisoners receive even more brutal treatment from the guards. While incarcerated, Max meets Horst, an inmate who proudly wears the pink triangle. Max and Horst fall in love with each other, and Horst's bravery leads Max to accept his sexual identity.
