The part of the movie I saw involved a gang in a house. In one scene there was a young boy with his dog and the scruffy dog runs up the stairs.. the boy starts up the stairs where gang members are and the lady has to chase him up and stop him. There is a scene on a beach where a handsome young blonde guy with a buzz cut makes a pass at a young woman, she refuses him and he strangles her off camera. The rest of the gang hear about a young woman found murdered on the beach... on the radio... and they know who it is. I didn't recognize any of the actors.
