Saat po long 2

When an undercover cop gets too close to revealing the mastermind of a drug syndicate, his cover is blown. Double-crossed and under a false identity, he's thrown into a Thai prison, where a guard discovers the inmate - claiming he's a cop - is a bone marrow match for his dying daughter...and his warden may have an even deadlier operation hidden within the prison walls. In this giddily frenetic follow-up (though not a sequel) to modern martial arts epic Kill Zone (aka SPL: Sha Po Lang), action icons Tony Jaa (Ong-Bak, The Protector) and Zhang Jin (Ip Man 3) team up with Hong Kong megastars Simon Yam, Wu Jing, and Louis Koo for a breakneck story of dirty cops, prison riots, and black market organ transplants, all brought together by a non-stop series of inventive, bone-crunching setpieces.
