Captain Alex, one of the most decorated officers in the Uganda People's Defence Force, is sent out to capture the crime boss Richard and his Tiger Mafia, a criminal organization that controls the drug trade of the city of Kampala. Alex sets up camp in the village of Wakaliga. After doing so, his soldiers go to a bar where a fight ensues between them and the villagers. Alex breaks it up and takes them out of the bar.

Alex and his soldiers locate the Tiger Mafia during a drug deal and infiltrate it. In the following fight, Richard's brother is captured. Richard berates his men, shoots his wife Ritah in his fit of rage, and then swears revenge against Alex. He orders a spy to seduce Alex in his tent and sends the mafia to capture him later that night. However, Alex is killed by an unknown source, leaving the mafia and his soldiers in disarray.

Captain Alex's brother, a Ugandan shaolin monk named Bruce U[note 1] arrives at Kampala the next morning in search of the murderer and finds a Tiger Mafia card in Alex's tent. Elsewhere, the mafia tells Richard that Alex is dead; Richard becomes irate because he wanted Alex brought to him. Bruce goes to a shaolin temple where he fights the other martial artist until the master appears. Bruce asks the master for help on his quest for vengeance, but the latter declines.

Bruce goes to the forest to train for his quest on his own. After sleeping in a tree, he discovers Ritah, who has amnesia after being shot by her husband. Bruce, unaware that she was part of the Tiger Mafia, comes to her aid. After training in a nearby lake, he discovers that Ritah was a member of the mafia due to a tattoo with the mafia's initials. Ritah regains her memory and agrees to take Bruce to the Tiger Mafia base.

The UPDF hires a new military leader who formulates a plan to attack the mafia's base. However, his plan is overheard by Richard through the phone of a turncoat police officer. Richard gathers the mafia at the base to prepare and sends one of his men to steal an attack helicopter to bomb Kampala to serve as a distraction for the government. Bruce invades the mafia's base, but is captured and brought to Richard, who orders three of his men to fight him with combat skills. Bruce holds his own for some time but is eventually overwhelmed. The military bombs the base with a helicopter, forcing the mafia into a forest where they fight the UPDF.

After the chaotic fighting, the entire mafia is dead and only Richard remains. He strips the gun off one of his deceased men, kills a number of soldiers, and takes down the military helicopter but is eventually shot and captured. The Ugandan government places Kampala under martial law, and the film abruptly ends as the Video Joker thanks the audience for watching.
