Three martial artists-notorious in their prime as "the three tigers"-have grown into middle-aged men one kick from a pulled muscle. But after their teacher's murder, they must juggle dead-end jobs, dad duties, and old grudges to avenge him.

After giving up Wing Chun, Cheung Tin Chi (starring Max Zhang) ran into trouble with the local triad and had his home burnt to the ground. He took shelter on Bar Street and found solace from the neighbours. But when he discovered the triad was peddling drugs on Bar Street, Tin Chi took it upon himself to intervene. When the drug lord sought revenge and killed Tin Chi's friends, he decided to take on the drug lord in a final showdown.
