Director Donald Crombie's fourth feature tackles the problem of out-of-control redevelopment by unscrupulous corporate developers. Angel Street is a row of charming and quaint homes on the shore of Australia's Sydney Harbor. A development company wants to buy the homes, raze the street, and build high-rise apartments in their wake. When B.C. Simmonds (Alexander Archdale), the leader of the residents' group, dies under mysterious circumstances, his daughter Jessica (Liz Alexander) takes up the residents' cause against the developers, assisted by Elliot (John Hargreaves), the Communist union official with whom Jessica had a brief affair. It turns out that the developers are not just businessmen, but have a malevolent connection with the government.
