The premise doesn't seem bad, that the school is relocated due to the fires and a group of thieves want to recover money hidden in the place where the new school is. However, it doesn't feel like a St. Trinian's film to me. Its the only one in color and of the characters from the other films only Harry is still there. There is no more Sargeant Gates, which would have helped. The movie goes along at a decent pace and Frankie Howerd is, of course, a good comic actor, but the film is watchable only because its part of the series not because it is such a great stand alone film. See it if you want to complete your watching of the original St. Trinian's films, but otherwise it is not essential viewing.
