Stanley Baker plays a Liverpool police detective who is reassigned to a special Juvenile Liassion Department, which takes this film into the world of a large public housing project teeming with youth of all ages who are seemingly teetering on the edge of becoming responsible adults or the criminals the movie portrays, played quite well by David McCallum and the other tough actors who play his hoodlum friends and followers. There's an awesome opening shot of McCallum and his boys within the confines of the project, and the film interjects Baker into this world through his relationship with two childhood twins who play McCallum's younger siblings, and their older sister, whom Baker begins to fall for. Things get a little bit unbelievable as the film progresses, but the focus on alienated youth bopping along to a rock and roll song isn't half bad, and the conclusion, which seemed to me to be too much of a stretch, was still shockingly well done.
