Purple Storm

Kieron Chow, a Khmer Rouge terrorist, arrives in Hong Kong with his unit to carry out a mission. During the operation, his son Todd, who is also his loyal right-hand man, suffers a severe head injury that leaves him with amnesia after waking from a coma. Todd is given a new identity, but this new life puts him in danger. Psychiatrist Shirley Kwan assists anti-terrorist officer Mark Chan in convincing Todd that he is actually an undercover police officer assigned to infiltrate his father's terrorist group. As Todd gradually recovers pieces of his lost memory, he faces a difficult decision between his violent past and the chance for redemption offered by his new role.
