Where to Watch I am William (2017)

William's father is dead and his mother is mentally ill, so he lives with his uncle Nils. Nils is on early retirement, making money by buying things cheap and selling them high. He has also accumulated a large debt and city's gangsters are on him, demanding that he pays it full. William sets out to pay off the debt of his uncle - and perhaps his courage might impress Viola too, a girl from his class.
