Sam Sandell, an American engineer working in India, is attacked by a tiger but rescued and nursed back to health by Chameli Brentwood, a half-caste. Sam's subsequent marriage to Chameli angers her uncle, Sathoo Ram, and Raj Singh, a former suitor, and results in a plot to destroy Sam and his dam. Sam's onetime English sweetheart, Harriet Halehurst, on the other hand, takes the marriage well and even accepts Chameli into society. Chameli proves to be faithless and is killed by a bullet meant for Sam, who has again been saved from a tiger--this time by Harriet. Sathoo, Singh, and their fellow Thugs succeed in breaking the dam; Sam is reunited with Harriet after rescuing her from the flood.—AFI
