In the United States in the last century, the male protagonist (Johnny Knoxville) owned a dilapidated amusement park "Action Park" when he was young. In order to save the home in his daughter's mouth, he called on all employees and friends, and everyone gave the amusement park a new attribute: excitement. Visitors can do whatever they want, and there are no rules at all. All facilities in the amusement park can be destroyed, so the theme park created by these daredevils has become the most popular attraction in the city.
