Charly was a clown before he lost his talent for making people laugh. When Charly loses his last engagement, he decides to take his own life. He jumps off a bridge under which Karla, a notorious merrymaker, is disposing of her latest victim. His suicide attempt fails, so Charly blackmails Karla: either she kills him or he betrays her to the police. Karla is a lust murderer, she only kills who she loves - and Karla simply can't feel anything for the world-weary clown. When all attempts to kill her fail miserably, Charly has a plan: laughter is the best aphrodisiac. Charly wants to make Karla laugh, make her fall madly in love with him and then finally be able to kill him.
