At first it looks like Emily Yan, the daughter of an ultra-wealthy Chinese businessman, is the unlucky victim of a carjacking gone wrong. But when her father is unable to contact either her or her hard-partying younger brother Charlie, he calls in ex-military bodyguard Ryan Lock and his partner, retired US Marine Ty Johnson, to find his children.
Lock and Ty soon find themselves plunged into a unpredictable spiral of violence where every new victim brings with them more questions than answers.
With the family refusing to involve Los Angeles law enforcement, it’s down to Lock and Ty to track down Emily and her brother. Standing in their way is a merciless killer known only as the Red Tiger.
