We dive right into the thick of the action within the first minute of The Price of Free, as Nobel prize-winner Kailash Satyarthi and the Bachpan Bachao Andolan (BBA) take us along on a raid at a workshop using child labour. The activists break open locked doors and turn the place upside down in search of trafficked children, who are cowering under furniture or trembling under piles of raw materials.

The documentary, directed by Derek Doneen and produced by Davis Guggenheim (maker of He Named Me Malala), traces Satyarthi's life's work, rescuing thousands of children from dingy, stuffy workshops, where they make cosmetics, jewellery and toys they'll never get to play with.
