Fifteen-year-old Mia (Katie Jarvis) is in a constant state of war with her family, her school and her neighbors, without any constructive creative outlet for her energies save a secret love of hip-hop dancing. When she meets her party-girl mother’s charming new boyfriend Connor (Michael Fassbender), she is amazed to find him returning her attention, and believes he can help her start to make sense of her life—though his seemingly tender demeanor may hide a much more treacherous interior. A clear-eyed, potent portrait of teenage sexuality and vulnerability, Fish Tank confirms writer/director Arnold’s stature as one of the leading figures of new British cinema.
