Last Step to Death (1983)

Original title: Ölüme Son Adım

Ultra hardcore mercenary Kaan, the kind of guy who carries an astonishing amount of large knives on his body at all times, is hired by some guy in a suit with a nervous tic (Patron) to rescue a Professor who has found the cure for leukaemia from some unnamed and unexplained heavily armed evildoers holding him somewhere out in the country. Tic guy is willing to pay Kaan 100 million TL for his efforts, so there's no reason for the mercenary not to take the offer...
