St. Trinian's is an all-girls school run by the quirky headmistress Ms. Camilla Fritton. When the newly appointed minister of education shakes things up and tries to take them down, the girls have no choice but to rise to the occasion. After all, they excel at chaos and attitude and that's exactly what it's going to take to beat the authorities before they close down their beloved school for good. Now, the school will need the help of Head Girl Kelly and artful dodger Flash Harry to save the school from bankruptcy.
