In the Indian language of Bhojpuri the name ‘Bidesia’ refers to a person who has migrated to a foreign land. However, Bidesia is also the name of a genre of Bhojpuri folk music, which reflects the history of the pain and loss of the indentured labourers who migrated from the states of Uttar Pradesh and Bihar from the 19th century. This film is a journey to find the last musical expressions of this history still present in contemporary artists, whose songs tell the story of millions of forgotten Indian slaves who laboured on plantations and construction sites throughout the British colonies.
