The Tracker

Spears, a private detective working in L.A. receives word from an old friend that the friend's sister (and Spears' ex-girlfriend), Kim, has been kidnapped by a criminal gang. At first, Spears doesn't want to get involved, especially when he finds out that his friend's family is mixed up with the Chinese Mafia, but the feelings he still has for Kim lead him to return to New York and try to rescue her.
