A gang of seven boys commit a series of offences, increasing in severity from truancy to armed robbery. For a variety of reasons, the gang is reduced, one by one. Aims to dissuade children aged 8-15 years from committing offences. Intended for schoolchildren, parents, teachers, social workers and all who deal with children at risk.Seven wayward juveniles (the "Green Bottles" of the title) spend their days truanting and thieving. One by one they are caught and made to face the consequences of the choices they have made. An educational film apparently made in association with the Metropolitan Police and intended to be shown in schools as a warning to those who might be tempted to stray from the straight and narrow. Included as an extra on the DVD for Bronco Bullfrog (1971).
