Octane

A man and woman posing as paramedics assists a man in an overturned car on a freeway. As an ambulance approaches, the woman panics, taping the man's mouth shut and pulling him from the car before speeding away. Meanwhile, single mother Senga and her 15-year-old daughter Natasha 'Nat' are on a six-hour overnight drive home, following a visit to Marek, Nat's father, for her birthday. En route, they pass by the crash, and Senga notices a strange man and woman photographing the scene; as Senga watches them, the man turns his camera and photographs her.
