Tracker (2001)

Using his extrasensory powers, Cole figures out how Zin got his confederates into Chicago: by taking over the passengers on a train. Although Cole taps into the station's camera, he can't get a clear look at who they are. Meanwhile, an Inixian named Kaden is distributing an alien drug not only to his fellow criminals, but to humans as well. One of Jess' friends has a heart attack induced by the drug. Cole tracks the gas emissions caused by the drug production and follows Kaden to one of his traveling drug-clubs. Displaying a new ability to temporarily change his body, Cole duplicates one of the guards and manages to get close enough to Kaden to capture his life force.
