The movie begins in an Opera house during a concert. The cymbalist slowly falls asleep. The conductor looks panicked, as it’s her moment to play. Fortunately, the musician next to her wakes her up by playing 3 notes in her ear, so she can finish the song.

The same scene happens, with the same characters, but this time, in a car. Except this time, it’s not the musician, but the Driver Fatigue Sensor technology of the car that wakes her up.
