A Finnish man goes to the city to find a job after the mine where he worked is closed and his father commits suicide.
Iris is a shy and dowdy young woman stuck in a dead-end job at a match factory, who dreams of finding love at the local dancehall. Finding herself pregnant after a one-night stand and abandoned by the father, Iris finally decides the time has come to get even and she begins to plot her revenge.
The story bases on four Finnish brothers, nicknamed 'the Eura Daltons' who received nation-wide notoriety for tearing gas pumps apart when they needed cash.
