Dead Aim(1987)

Ed Marinaro is Malcolm "Mace" Douglas, a street-tough detective who's out for justice-no matter what the cost. While investigating the mysterious suicidal heroin overdoses of four beautiful exotic dancers, Mace puts together the pieces of a deadly puzzle, infiltrating a violent ring of shadowy drug and weapons dealers, Mace methodically tracks a serial killer (Rick Washburn) with murderous ties to a ruthless foreign diplomat (Harry Goz). Mace won't stop until he gets some answers. The FBI and KGB have them, but now they're talking back with bullets.
