The story of four young Australians trying their luck in 1960s London.

Two social workers reach breaking point with the heartless welfare system which treats destitute children as criminals. Reaching out to these children means entering into the world of drain kids, pinball parlour pimps, graffiti gangs, the 14-year-old dealers and their 12-year-old customers. It's an exhausting and sometimes dangerous occupation but they care about the kids with a passion and the successes make it all worthwhile.
