Liverpool. 1947. Right after World War II, a star struck naive teenage girl joins a shabby theatre troupe in Liverpool. During a winter production of Peter Pan, the play quickly turns into a dark metaphor for youth as she becomes drawn into a web of sexual politics and intrigue and learns about the grown-up world of the theater.
Unfortunately the movie An Awfully Big Adventure is not yet available on HBO Max.
