Nora is a night shift driver for a ride-sharing company. She is addicted to amphetamines and her life is falling apart: she is heavily in debt and divorced. Now she sleeps in the car, saves enough money to rent an apartment, and obtains joint custody of her daughter. When her brother Ben (also a driver) crashed the car, Laura offered to send him a strange package, but was generously paid. Unaware of this, Laura is now trapped in a mysterious and dangerous underground network. Tonight will be the darkest night of her life.
