This creepily compelling film unfolds with the disordered logic of a fever dream, as a 13-year-old girl follows a blood trail that leads from her first period to an Afghan boy shot by drug dealers who’ve used him to smuggle coke. Dutch director Paula van der Oest, whose Zus & Zo was nominated for an Oscar for best foreign film, coolly pushes her heroine into extreme displays of teen angst as she and her “patient” flee a persistent assassin. Along their weird, picaresque journey they disguise themselves as handicapped sisters in matching first-communion gowns and later land in a deserted 15th-century Luxembourg town house, where they experiment with sex and drugs. Laurien van den Broeck’s masterful unblinking performance transcends the uneasy all-English dialogue; her costar, who speaks no European language, stays largely silent.
