Lin Hao, a young man from a water town, is about to get married. Pan Dagui, a fellow villager, has harbored resentment ever since his investments failed years ago, blaming the Lin family for his misfortune. On the eve of the wedding, he shows up to cause trouble and plans to use a 100-ton crane to block the only stone bridge, hoping to extort money and disrupt the wedding procession's auspicious arrival time. Lin Hao senses the danger in advance and joins forces with village and township officials to prepare a response. Faced with his unreasonable obstruction, everyone relies on rules and wisdom to overcome the crisis, protect the wedding, and ensure that his schemes come to nothing.
