The Horse Tail.

The ponytail is a dumpster version of the Oedipus myth. Diana, a prostitute from Vienna, returns to the city. She has a trace, memory gaps, and milk started flowing from her breasts. Twenty-year-old orphan-outcast May suspects that she may be its author. Diana's return coincides with one made in the neighboring forest. May is arrested for being violent on police officer Max's wife.
