Trama
Jett flies to Athens to deliver a package containing an inflatable muscle costume to little Nikos. Nikos is supposed to play Hercules in a play and believes he can only do it if he looks muscular enough. However, a small accident occurs during rehearsals. The costume inflates so much that Nikos has to take it off. Filled with so much air, it flies away uncontrollably and threatens not only to spoil the little boy's performance but also to cause great damage. Jett and his airplane friends naturally do everything they can to catch the broken muscle pack again.
