Norway is a country with a large number of road tunnels, but due to the lack of emergency planning and disaster relief facilities during the construction of the tunnels, fires in the tunnels are often fatal. Stan finally took a day off on Christmas Day and planned to spend a vacation with his daughter and his girlfriend, but Elise had a big fight with Stan because she was thinking about her deceased mother and got on a long-distance bus to Oslo. But shortly after Elise's bus entered the tunnel, the tanker truck in front of the bus had an accident, causing traffic in the tunnel to be blocked, and the bad weather prevented all rescue efforts from arriving in time. Then the tanker truck short-circuited and exploded, and the hot smoke instantly filled the tunnel. Elise led everyone to save themselves and took refuge in the maintenance hut in the tunnel. Stan drove into the smoke to find his daughter. The tunnel was filled with a large number of suffocated dead, and the hut where Elise and her friends took refuge was gradually filled with smoke. Finally, Stan appeared and saved Elise and several survivors. On the way back, the rescue center informed Stan that two little girls were trapped near them. Stan let his daughter and the survivors go first, and went to find the two girls alone. The little girl was found, but Stan, who had given all his breathing equipment to others, could not hold on and lost consciousness. In a trance, he found that his daughter Elise had returned. She helped Stan notify his teammates and female companions, and everyone rescued Stan, who was about to suffocate, from the thick smoke and landslide. In the end, although the accident caused great casualties, the rescue team members' desperate actions still saved some precious lives, and Stan's newly formed family was also brought together by this life-and-death experience.
