Arinzé Kene’s play Misty is a collection of rap numbers and skits about a fare dodger, Lucas, from Hackney. Lucas (played by Kene) gets into a scuffle on a bus and is later arrested for entering London Zoo without a ticket. That’s the entire narrative. Obviously, Kene can’t create an evening’s entertainment from such meagre pickings, so he turns his tribulations as a dramatist into the show’s second storyline.
