Freeway Rhapsody (2000)

Jeff is doing his first day of work on the highway. He was hired as a maintenance agent to see his old love, Périnne, who works at the toll. While picking up blocks on the emergency lane, his left ear is severed by a disc accidentally ejected from a car window. First shocked by the accident, Jeff realizes shortly after that he continues to hear from a distance with his ear cut off. Jeff begins to search for his ear, letting himself be guided by the sounds he hears.
