A Melbourne family is very happy living near the Melbourne airport. However, they are forced to leave their beloved home (by the Government and airport authorities) to make way for more runways. 'The Castle' is the story of how they fight to remain in their home.

Jason Blade is a man who can't bring himself to commit fully to his woman, and who spends all his time with a special crime task force taking on assignments to fight crime and right wrong do-ers. When his love is kidnapped by his arch-enemy the race is on to get into the power station where she is being held and battle an army of ninjas. Only then can he face Baxter, his arch-enemy, and stop a bomb from exploding to save his sweetheart, and show her that he is a man. A man who can commit. A man who is strong.
