Movies like St Trinian's 3: Battle of the Sexes

St Trinian's 2: The Legend of Fritton's Gold is a 2009 British adventure comedy film directed by Oliver Parker and Barnaby Thompson, both of whom directed the previous film in the series. It is the seventh in a long running series of films based on the works of cartoonist Ronald Searle, and the second film produced since the franchise was rebooted in 2007.

A sequel, St Trinian's 3: Battle of the Sexes, had been in development since 2009, but was never produced.

One night, the girls of St. Trinian's catch Celia, a member of the eco sect, retrieving an old ring from the school's Fritton Archives. Celia explains that an unknown man telephoned her to retrieve it for him in exchange for £20,000. Seeking to get more, Annabelle Fritton, the new head girl, demands £100,000 from the man when he calls back, only for him to refuse and threaten the girls for their greed. When the school's power is cut, the girls ask their headmistress, Camilla Fritton, about why the ring might be so valuable.
