Grimm

One winter day, Jacob (Jacob Derwig) and his sister Marie (Halina Reijn) are left in a wood by their out-of-work father, with a letter in his jacket pointing them toward an uncle in Spain. The uncle is dead when they arrive, and Marie falls for Diego, a wealthy surgeon, while Jacob watches with growing jealousy. Alex van Warmerdam builds the film on a plain fact: a sibling who has been each other's whole family cannot easily share the other with anyone.
