Private detective Germán Areta el Piojo investigates the life of a gay man who has apparently abandoned his partner. When they both turn up dead, it seems one killed the other before committing suicide, but Areta is not convinced.
Unfortunately the movie El crack dos is not yet available on HBO Max.
