Tony Jaa and Wu Jing star in this bone-crunching martial arts spectacular!

TTen years after Wilson Yip's martial arts blockbuster, SPL (SHA PO LANG) became a breakout hit, a follow-up starring Tony Jaa (ONG BAK), Wu Jing (SHAOLIN), Simon Yam (IP MAN), Zhang Jin (RISE OF LEGEND) and Louis Koo (DRUG WAR) has finally arrived. Although a sequel only in name, it is bigger and more action-packed than fans of SPL could have ever hoped! Undercover cop, Kit (Wu Jing) becomes a junkie in order to catch Mr Hung (Louis Koo), the mastermind behind a crime syndicate. When the operation goes sour and Kit blows his cover, his supervisor and uncle, Wah (Simon Yam) decides to terminate the operation. When Kit disappears without a trace, Wah defies the order from his commanding officer and tracks Kit to a prison in Thailand. Thai Police officer Chai (Tony Jaa) has taken a job as a prison guard in order to raise money for his daughter's leukemia treatments. Hes assigned to keep an eye on Kit. Even though Chai and Kit are in opposing positions and they dont speak a common language, Kit turns out to be a suitable bone marrow donor for Chais daughter. While Chai is determined to keep Kit alive, the warden (Zhang Jin) wants him dead to ensure the smooth operation of the prison, which is a front for Mr Hungs organ trafficking business. When Mr Hung shows up in Thailand for a transplant operation to save his own life using his younger brothers heart (Jun Kung, TIME AND TIDE), the stage is set for a showdown
