The uniformed but rebellious students of a distinguished all-girls school get an unexpected chance to raise a little hell as directors Oliver Parker and Barnaby Thompson set out to revive the characters created by comic artist Ronald Searle and made popular in the British film series that began with 1954's The Belles of St. Trinian's.
When their beloved school is threatened with closure should the powers that be fail to raise the proper funds, the girls scheme to steal a priceless painting and use the profits to pull St. Trinian's out of the black.
