The film tells the story of the beach guard team helping the police crack down on a criminal activity after overcoming many difficulties. The team members cooperated very tacitly. The new team members grew up slowly in this activity and were recognized by the old team members
At the beginning of the movie, the beach guards help everyone to protect safety on this beach. Some simple rescue activities. For example, when someone accidentally fell into the water or suddenly some fires broke out on the beach and other unexpected situations, the beach guards will be dispatched quickly to help the people solve these problems. At this time, the Beach Guard team began to select new members, and among the new members was a former World Cup swimming champion. He was not convinced. The old players felt that their level of strength was much better than some old players. After all, he was the World Cup champion. But in the subsequent work, he found that his thinking was too shallow.
