Set in 1925, "Prisoners of Paradise" follows 17-year-old orphan Lucy Gladwell (Ellie Bamber) who is sent from England to live under the guardianship of her uncle George Huyton (Rupert Penry-Jones). Initially seduced by the sumptuous beauty of her surroundings, Lucy finds herself at odds with her violent uncle who is not the benign influence he pretends to be, and she soon falls in love with Krishna (Mehdi Dehbi), a laborer working on a nearby plantation.
