Just married Hong Kong couple Chen & Lily emigrate to England, soon to become parents to a little baby boy and generally struggle through life. Chen works long days in a restaurant, while Lily does the housekeeping, daydreaming of setting up their own business, much to Chen's chagrin. When Chen lets his colleague Fok seduce him down a path of mounting gambling debts, he is recruited as a drug courier for a shadowy Chinese triad. Suddenly he realizes that getting their own enterprise could be their only means of escape.
