Years ago, between 2007 and 2010, I was watching TV and while flipping through some channels I stopped to see this one particular scene from a movie that has stuck in my mind ever since.
The scene that I saw involved 2 men: one in a car and one outside. The two were having some kind of argument and then the man on the car rips off the hand of the man outside and blood splatters all over the windshield, while the man in the car had a very smug expression about it. The scene changes to show the man runs into a pond and pours water over the wound.
That's all I remember from it, I changed the channel during the pond part. I also remember that I watched this on Canal 5 of Mexico, which air mainstream movies and sometimes Mexican ones, but I'm quite sure this was a foreign one, most likely American. Also the scene kinda gives me a feeling that the movie was probably from the 70's or 80's.
