In a Year of Thirteen Moons

When his wealthy male lover dumps him, Erwin Weishaupt makes a desperate attempt to win his man back by having a sex change operation. But the sacrifice is doomed to failure, and as time passes, the doubly-rejected Erwin, now Elvira, is beaten down by the cruelties and utter loneliness of her life. The relentless despair eventually deepens to the point where she can no longer sustain herself -- and chooses to take her own life. (official distributor synopsis)
