Sky On Fire

Five years ago, a fire took the life of Professor Poon, and his research notebook disappeared without a trace. His assistant Ko Yuk (Zhang Jingchu) escaped death after being rescued by security guard Chong Tin-po (Daniel Wu). After losing his wife to cancer several years ago, Tin-po entered Sky Number One, a top-level medical facility financed by the tycoons, as a security guard. He hopes that the lab will finally find a cure for cancer, but he realises that Ko Yuk is the only researcher that is actually trying to develop "Super Stem Cells" to save lives. Meanwhile, her husband, Sky Number One president Tong Wing-cheung, is a ruthless businessman who puts money ahead of everything and will take any means necessary to get his way. The "Super Stem Cell" has finally been successfully developed. Chia-chia has brought his cancer-afflicted sister Jen to Hong Kong in search for a cure, but they're suddenly caught in the middle of a daring robbery for the "Super Stem Cell". The man behind the robbery is Professor Poon’s son, Poon Chi-man. To discover the truth behind his father's murder, Chi-man engages in an explosive battle against Tin-po and his security team. Tin-po fights to protect the stolen cancer cure, and Chia-chia needs to steal it to save his sister. When the two men realise that Chi-man and his team are the good guys after all, they face a moral dilemma: Should they betray Chi-man or help him defeat the tyrant that is Tong Wing-cheung? Prepare for an all-out war that will rock the city!
