Dennis's dad is to sick to come to work, so Dennis hands in a sick note to find out what Dad's work life is like...only due to a mix-up Dennis & Gnasher find themselves instead at the Secret Agency next door where they are mistaken for Dirk Cool, a secret agent who is a master of disguise dressed as a 10 year old boy and his dog. Next thing the duo know, they are being fired of in a space pod on a mission to stop a crazy dinner lady turn the whole world into 10 year olds unless they eat her rotten dinners! Can Dennis and Gnasher save the day?
