Housewife Britt-Marie's 40-year-old marriage has just broken up because she learned her husband was unfaithful. Now, at 63 years old, she is faced with making a new start in life in the small town of Borg. Told she is a nagging passive-aggressive aunt, the only job she can find is quite challenging: to coach the town's youth soccer team. She knows nothing about soccer or coaching, and the team is the town's pride and joy, but she takes the job anyway.
