Soft (2007)

Dad (Jonny Phillips) gets home and wants his teenage son "Scott" (Matthew O'Shea) to go get some milk. Ignored, he goes himself and encounters a gang of exhibitionist hoods who knock him to the ground. On returning home, he discovers that his bruised son also encountered these thugs earlier and when quizzing him about fighting back, realises that they and their ring-leader (Michael Socha) are now sitting on a car outside their window, goading them. What to do now? Call the police? Keep quiet and ignore them or confront them? What does happen is hardly expected and really quite effectively thought-provoking.
