Borgman (2013) on Netflix

Plot summary

Camiel Borgman lives in an underground den with companions Ludwig and Pascal, until an armed priest and two other men drive them out. He hitches a ride into suburbia and reaches the door of a large house belonging to Marina, an artist, and Richard, a media executive, who have three small children and a nanny, Magot. Camiel says he knows Marina and that she nursed him in a hospital, and he asks for food and a bath. His manner provokes Richard, who beats him and leaves him wounded. Marina, moved by guilt and curiosity, hides him in the garden shed without telling her husband. Their youngest child, Isolde, noticed him early.
