At first he is just relieved to be away from home, but he soon realises that there's something really weird going on at Crammer Grammar…
As Frankie tries to find out the secrets of the school he discovers that the headmaster, Dr Gore, has plans to turn all the students into robot-like super-brains using his Brain-drain machine! With the help of his new friends Neet and Wes, Alphonsine his crazy French nanny and a poodle named Colette, can Frankie save the day before it's too late and change the F-for- failure to F-for-fantastic?
