In Matt Parvin’s first full-length play Jam, Bella Soroush (Jasmine Hyde) is a teacher at one of the high schools in a rural part of the South West. She used to teach at the other local school until an incident with a pupil, Kane McCarthy, ten years earlier. It was an event that scarred her and nearly ended her career, but she got back on track, and is alone at her new school one night, marking papers when Kane (Harry Melling) breaks in with a baseball bat. He says he isn’t going to harm her and she lets him have his say, but she’s clearly still afraid and no wonder: A chaotic presence at 13, with ADHD, dyslexia and an obsession with elaborate pranks, he still seems volatile at 23. He says he’s returned now because he’s got a brain tumour and has been given six months to live, and wants to tie up loose ends in his life; his story is detailed but Bella isn’t quite prepared to accept it isn’t a new and particularly dark practical joke.
