It is only a fleeting glimpse of the great International Marxist Group activist, but it is most certainly him (at 1:12).
Samir Sahni is a farmer living with his mom, dad, wife, Rama, a young daughter, and his younger brother, Veer. Samir gets an offer to work in the U.K., and departs accordingly. He would like to settle there, and after doing so, would like his family to also join him. The years go by, and Samir keeps in touch with his family regularly. Then the Sahni family stop receiving any letters from him, and are anxious to know what has happened to him. Veer is asked to travel to U.K. to find out, and he does so.
What he finds are tens of thousands of East Indians on fake passports, working for less than minimum wages, poor unhealthy conditions, fear of being deported, and paying half of their earnings to fellow East Indians who had got them here through the underground. Veer finds no sign of his brother, and sets out to investigate, only to find deceit, murder, and his very own life in danger.
Lots and lots of super nostalgic footage of the 1970s.
For some, not much has changed. Even Tariq Ali is still about.
