Killer Trench

The "Killer Trench" fighting competition in the United States is about to kick off. Two Chicago-area gangsters are aiming to win the game, and one of the ace players - Killer King Lee has a high reputation. Young Aaron (Jackie Chan) and his family run a hotel in Chicago. Aaron's father is blackmailed by gangsters. Aaron tries to drive away the bad guys, but his father complains. It turns out that Aaron's father has always been dissatisfied with Aaron learning martial arts from his younger brother. Aaron's experience teaching the gangsters was seen by Peng, the second-generation leader of the gang. Peng intentionally asked Aaron to fight in the killer trenches for them. The gang where Peng belonged to immediately beat Aaron's friends and kidnapped Aaron's unfaithful sister-in-law to force him to fight the killer king. Aaron and his uncle failed to save people, so they had no choice but to train hard and represent Peng and his gang in the competition. Aaron won consecutive victories in the game, but in the final match between him and the Killer King, Peng betrayed him...
