Yang Mo has had a dream of becoming a hero since he was a child. He imitated the masters in TV dramas who jumped off cliffs to gain peerless martial arts, and after falling, he suffered from habitual dislocation of joints. Now he is a security guard who works diligently. He encountered an obscene man on the bus, but was framed for his bravery. On the last stormy night before he was fired by his boss, he encountered a thief stealing a batch of meteorites while patrolling the warehouse. It turned out to be his colleague and childhood friend Wu Kui. Facing a homemade earth gun in Wu Kui's hand, Yang Mo decided to sacrifice himself for justice, but he didn't expect that a lightning bolt in the sky struck the meteorite, time and space were distorted, and time went backwards.
