The O2

The schoolgirls start a new term amidst the usual chaos and excitement. Rupert Everett returns as unconventional headmistress Camilla Fritton and Colin Firth as her old flame Geoffrey Thwaites. A rollercoaster-style treasure hunt for the legendary Fritton’s Gold ensues as they face their most fearsome establishment rivals yet, but the feisty and ever-resourceful girls of St Trinian’s are undeterred in their mission to outwit the villainous Pomfrey and his sidekicks from the women-hating secret society known as AD1.
