Great Movie
Best scene in the movie is when after Norris chases the kidnapper into the river and the kidnapper is run over by the boat. The scene when he is dripping wet and he goes over to Diana Luna and confirms to her that her mother was killed. The great facial expressions by Molly Hagen and the reaction of Eddie Kuzak by putting his arm around her to comfort her made this much more than just your run-of-the-mill cop movie.
Norris and Davis would have been smart to continue this in sequels
