Ladies of Steel is a dark comedy movie about three elderly sisters who embark on a road trip, bringing them together to confront their past and deal with the challenges of aging.

With elements of humor and drama, the film explores themes of love, death, and the complexities of family dynamics.

While at the reception, Inkeri overhears the doctor telling the nurse behind the corner that there is no life expectancy or hope left. Inkeri's daughter Maija takes it upon herself to care for her mother, even if it means forcing her, but Inkeri has other plans. As her last act, she intends to save Maija from repeating her own mistakes and then throw herself into the Arctic Ocean. Inkeri escapes from the nursing home for her final journey with her steel-haired friends and Matti, who has tagged along. Before reaching the Arctic Ocean, Inkeri throws herself into life: painful memories, intense emotions, and forest rave.
