Throughout the 1990s, three teenagers endure brutal Kung Fu training under their master’s constant watch. Swearing loyalty to their teacher and each other, they hone their skills in secret challenge matches, defeating rival schools and building up a fearsome reputation as “The Three Tigers.” After growing apart for twenty years and failing to live up to their potential, the former prodigies are reunited when their master is mysteriously killed. Despite past grudges, personal struggles and being terribly out of shape, the old Kung Fu brothers must band together against hitmen, rude waiters and social media influencers to avenge their master’s death.
