A cross-country airliner, whose passengers include a nuclear physicist, a rocket expert, and a mathematical genius, is drawn beyond radar range by an unknown, unbreakable force.

Timmy Lea and his brother-in-law Sidney Noggett are working as entertainment officers at Funfrall, a typical British holiday camp. The staff are lazy and inefficient, preferring to laze by the pool rather than organise activities for the holiday campers. A new owner, Mr. Whitemonk, an ex-prison officer, takes over the camp and is determined to install discipline into the staff. He is on the verge of dismissing Timmy and Sidney; however, Sidney's suggestion of organising a beauty contest changes his mind.
