The undersea tunnel connecting Manhattan and New Jersey is a local transportation hub. Once, an accidental explosion caused the tunnel to be blocked. Many innocent citizens were besieged inside, and their lives were threatened at any time. The police on the ground learned of the accident and immediately dispatched a large number of people to the scene, but they were helpless because the tunnel entrance was blocked and poisonous gas permeated inside. At this time, Ledullo, the former lifeguard captain who has been dismissed, arrives. Out of professional instinct and a strong sense of saving people, while he was arguing with the police who dared not act, he insisted on risking his life alone and entered the dangerous hellish tunnel through the flying tunnel exhaust.
Facing the sudden arrival of Le Dullo, the people in the tunnel were delighted, but when they realized that Le Dullo was alone, everyone fell into extreme despair and even suspicion, mocking Le Dullo's brave behavior. Under the influence of Le Dullo's selfless actions, everyone abandoned their mutual complaints, and the optimism of survival gradually grew in their hearts. However, the ensuing landslides and seawater flooding continue to stifle people's only hope. Under the leadership of Le Dullo, everyone finally united and worked together to overcome the threat to life again and again, and the flame of hope reappeared in everyone's hearts. However, unexpected events have overcome one difficulty, and they are faced with more huge challenges. Finally, Le Dullo realized that the escaped mice could help them move towards the light. Following the group of mice, people finally walked towards survival step by step. However, in order to save a long-term house dog, Le Dullo unfortunately got into trouble again, and in order to help him get out of the trouble, another woman who was unable to save was also caught in a sea of misery. Under the guidance and help of Le Dullo, everyone finally lay exhausted on the stretcher of the ground rescue team, but Le Dullo and the other woman were still alive or dead. The two Le Dullo who had gone through hardships pinned their last hope on the only piece of explosive. After a loud noise, a big mouth exploded on the top of the tunnel, and the huge suction finally lifted the two of them out of the sea.
In the light of the sun, Le Dullo was once again regarded as a hero by everyone. People once again called him the "captain", and Le Dullo had no intention of this. What he felt at the moment was just a spontaneous sense of justice
