Lautlos

Viktor, a methodical hit man, probably on his last job, has no plan for his retirement. He does not kill Nina, a woman sleeping beside his latest mark; then he follows her and rescues her from an attempted suicide. Nina is attracted to him, but also wants to know who he is. Her pursuit of his identity crosses the investigation of Lang, a brilliant police investigator who tries to inhabit the minds of the victims and the killer. (imdb)
