'Jack Flange takes a job as an oyster farmer on the Hawkesbury River, north of Sydney. To help his sister, who's recuperating after a car accident, he robs an armoured van at the Sydney Fish Markets and immediately mails the money to himself. The money never arrives and he begins to suspect the close-knit community on the river, even Pearl, the girl he's falling in love with. Meanwhile his boss, Brownie, believes his oysters are going bad because his wife has left him. Brownie's Irish father plots a strategy to solve all their troubles.'
