Je Tu Il Elle (1974)

For more than a month, eating only powered sugar, a woman tries to deal with a breakup: she paints her room twice, removes the furniture, writes and rewrites a letter to her lover, clarifying all she had said. She spreads the pages on the floor. She lies down and waits. Finally, her sugar eaten, she is hungry and leaves. She flags down a truck; she and the trucker drive through the dark, stopping at a diner and bars. He asks for a hand job, she complies. He talks about his wife, children, and sex life. She arrives at the flat of her lover, a woman, who tells her she cannot stay. She says she is hungry, so her lover feeds her then allows her to stay the night. They make love.
