Antibodies (2005)

Long wanted serial killer Gabriel Engel gets arrested in a spectacular police strike. Small town cop Michael Martens travels to the big city to interrogate him. He associates a brutal murder case with the killer's method and hopes to close the case by getting a confession from Engel. Instead the clash of the two totally opposite characters shakes Michaels beliefs to the ground, turning him into a dangerous threat, an enemy to the people around him.
