Ruth is a widow who lives alone, her grown sons in other countries. Frida shows up at her house one day, a carer from the government she says, here to help out with the cleaning for an hour a day. Eventually the single daily hour turns into hours. Frida stays for lunch. Sometimes she makes dinner. When Ruth invites an old friend to stay with her for a weekend, Frida offers to stay the weekend too, just to help out. When Ruth discovers that Frida’s moved into her guest room, she’s mad about it, but Frida gets more mad, and by the end of the weekend, Ruth can’t quite remember why she was so angry at Frida. And little by little, Frida steamrolls over this old lady’s life until there’s nothing left.
