In the film, an ex-Navy SEAL attempts to bring down a criminal organization that is benefitting from a dangerous drug called "Blood Heat."

[2] In the year 2009, CPO Joe Jinno (Kane Kosugi), a former U.S. Navy SEAL is sitting in a military jail cell in Roanoke, Virginia.

Japanese detective Aguri Katsuragi (Show Aikawa) has gotten amnesty for Jinno, whose refusal to kill terrorists because the enemies he found were scared children had him court martialed.

Two months later, Jinno was tasked by U.S. Secretary of Defense to join an undercover mission with Katsuragi to stop the circulation of Blood Heat, a new drug on the market that acts as a super steroid.

The man in charge of the drug's circulation, Lai Kenjin (Masaya Kato), has set up the Muscle Dome, an underground fight ring where his champion, Lee Son-Min (Ken Lo), uses Blood Heat and goes through his opponents with ease.

That night, Joe looks at a big screen TV and finds Aguri in the Muscle Dome, where he is viciously beaten by Lee and is crucified.

Meanwhile, Joe rescues a young girl named Haruka, whose father turns out to be the creator of Blood Heat and was forced to continue making it by Kenjin.

The youngsters are revealed to be orphans whose parents were victims of Kenjin, whether it was Blood Heat or losing major bets at the Muscle Dome.

The story for the film was created by Ushio Higuchi, the creator of the popular show Sasuke, known to American audiences as Ninja Warrior.

The film would be shot mostly in English and Japanese, but have a few scenes in Cantonese with the appearances of Jackie Chan Stunt Team member Ken Low and the late Hong Kong actor Joe Lee, who plays Kenjin's half-brother.

Chan, who befriended Kane due to Kane's friendship with Jackie's godson Sammy Hung (the son of film legend Sammo Hung), loaned Chan and Wong out for the film along with fellow stunt team member Antonio Carpio, who served as assistant action director.
