Watch How to Talk to Girls at Parties for free

In the '70s, punk-loving teen Enn (Alex Sharp) attempts to crash a party in the London suburbs. He ends up at the wrong house where he encounters a kooky, conformist cult, which includes the naive Zan (Elle Fanning). They hit it off before Enn learns that she is actually a repressed humanoid alien on Earth to complete a fatal ritual. Enn appeals to the punk scene to help both emotionally and physically liberate the lady he's fallen for. Directed by John Cameron MItchell. Based on the short story of the same name by Neil Gaiman.
