Produced by Gustav Oldén and Nicklas Wikström Nicastro, the film stars Pernilla August, Peter Haber, Anders Mossling, Malin Levanon, and Vera Vitali.

The plot follows the titular protagonist Britt-Marie, a 63-year-old homemaker played by August, who leaves her cheating husband of 40 years and reluctantly takes on a job as a youth soccer coach in the remote town of Borg.

Meticulously organized, she follows the same routine every day: making lists, cleaning windows, doing the laundry, preparing dinner for her husband of 40 years, Kent, who barely notices her.

[3][4][5] Pernilla August was praised for her performance in the lead role, with David Lewis from San Francisco Chronicle calling it "dryly funny, but also subtly affecting" and found it refreshing "to watch her heart and mind slowly but surely open up to life's possibilities".

[6] Trevor Johnston, in his piece for Radio Times believed that August was the film's "real star performer", arguing that "her deftly measured approach pays strong emotional dividends".
