Fatty Finn is the six-year-old leader of a gang of kids in Woolloomooloo. They enter Fatty's pet goat Hector in the annual goat derby, but his rival Bruiser Murphy lets the goat loose before the race. After a series of adventures, Fatty finds the runaway goat and persuades a friendly aviator to fly him to the race-track in time for the main event.
