According to a contemporary review:
Carrie (Kim Krejus) and Jeannie (Sonia Peat) have fled a corrective institution and must keep low profiles. Their experience has sharpened them to the needs of life in a harsh society, relying on wit and bravado to survive, Tom (Ian Gilmour) and Serge (Sergio Frazzetti), from a rural background, have not yet lost their innocence or acquired the toughness of the city-bred guys. The four try to make the best life they can together in their near impossible economic circumstances. On the way, they discover something special in the relationships that none of them has previously known.
The review argues that:
'What Duigan's film does is to convert these generalisations into realities.
'It gives us much more positive picture of what it is like to have to shoplift to fill your belly and avoid public nudity, to live in an urban cave in an abandoned warehouse beside which shunting trains provide an incessant accompaniment, to search without success for a job, to wait at home while your girl entertains lonely men for cash at a swank hotel, to live in a world without hope and to accept it because you don't know how to complain effectively. The film is grossly political without being polemical about it, yet in spite of its innate quality of waiting for the next heartbreak, warm and strangely comforting.
