Poto and Cabengo
Identical young twin girls in the USA have invented their own shared language. Scientists are wanting to study the language but social workers are trying to get the twins to leave their secret language world and enter the mainstream. This means forcing them to speak normal English and lose their secret language. The filmmaker's own questions about this process run across as text at the bottom of the screen, a first use of that technique in documentary. Written by Gillian Leahy
