Bartek Sowinski hid two Jews in his home during World War II. In an act of a crime incomprehensible to himself, he commits their murder. Years later, in 1971, while serving a sentence in prison, he records his confessions on tape for his two-year-old grandson Marcinek. These intimate memories are not only an account of the tragic events, but also a journey into the depths of his tormented soul, full of pain and questions about morality.
