Martin Durnley is a young man with an infantilizing mother, resentful stepfather and an institutionalized brother with Down's syndrome. To cope, he retreats into an alternate child personality he calls Georgie. After being caught during a theft attempt at a department store, he befriends a female customer who is sympathetic to him, but his friendship soon turns into obsession.
Unfortunately the movie Twisted Nerve is not yet available on HBO Max.
