The film opens up as a young prosecutor is handed her toughest assignment: a
truck driver charged with
reckless driving. She has to prove that he was negligent and kept falling asleep at the wheel. After crashing his
semi into a
sports car, his rig turns over, gas leaks out, and a fire ensues, shutting down the lights in the long tunnel. Unfortunately, due to the length of the tunnel it is impossible for rescue personnel to get in the tunnel to give adequate medical attention to the people seriously injured. There are several
flashbacks, where survivors recall the accident, including a grieving father named Giuseppe Paoletti, portrayed by
Flavio Insinna, an Italian family man who is driving his wife and son to Austria, who emotionally describes his account of what happened after the accident. ==Two versions==
