Even though Chai and Kit are in opposing positions and they don't speak a common language, Kit turns out to be a suitable bone marrow donor who can save Chai's daughter. While Chai is determined to keep Kit alive, the warden Ko (Zhang Jin) wants him dead to ensure the smooth operation of the prison, which is the front for Mr Hung's organ trafficking business. Mr Hung shows up in Thailand so he can use his younger brother's (Jun Kung) heart in a heart transplant to save his own life. The stage is set for a showdown...
