Compliance (movie, 2012)

Sandra is the manager at a fast-food restaurant, and Becky is her teenaged counter girl who really needs the job. One stressful day, a police officer telephones and accuses Becky of stealing money from a customer’s purse, which Becky vehemently denies. Sandra, overwhelmed by her managerial responsibilities, complies with the officer’s orders to detain Becky, beginning a nightmare that tragically blurs the lines between expedience, prudence, legality and reason.
