When 15-year-old Mia meets her mum’s new boyfriend, the teen’s world is turned upside down. Fish Tank, a 2009 British film, is a powerful slice of drama, but It’s not the only one you’ll be watching in the UK’s oldest cinema. Straight afterward, there’s The Goob to look forward to. Set in Norfolk, it simmers with resentment and revenge. Over 18s only.
