79-year-old Martha Anderson dreams of escaping her care home and robbing a bank. She has no intention of spending the rest of her days in an armchair and is determined to find a much more exciting life-style. Along with her four oldest friends - otherwise known as the League of Pensioners - Martha decides to rebel against all of the rules imposed upon them. Together, they cause an uproar with their antics: protesting against early bedtimes and plastic meals. As the elderly friends become more daring, their activities escalate and they come up with a cunning plan to break out of the care home and land themselves in a far more attractive Stockholm establishment. With the aid of their Zimmer frames, they resolve to stand up for old aged pensioners everywhere - Robin Hood style. And that's when the adventure really takes off...
