On a sunny Sydney wharf, Stacey and Stanley watch enviously as customers feed on as many hot salty chippies as they want. Fed up with having to scab for scraps with all the other seagulls, they seek out legendary chippy thief Steve-O to help them pull off the ultimate heist . . . But first they'll have to get past a seagull-hating chippy chef, deal with some bully bin chickens, and convince the World's Best Chippy Chaser to overcome his dark past and join the team.
