“John” was just days from turning 16 when he was allegedly recruited to work on a Brazilian coffee farm that supplies the global coffeehouse chain Starbucks.

Soon after his birthday, he embarked on a 16-hour bus journey to the farm in the state of Minas Gerais – only to discover that none of what he had been promised would be fulfilled.
