An aging gay couple owns a barber shop in the East End of London. One of them is a part-time actor about to go on trial for propositioning a police officer. The action takes place over the course of one night as they discuss their loving but often volatile past together and possible future without each other.
Unfortunately the movie Staircase is not yet available on HBO Max.
