Johnny Eaton, trouble-shooter for an American oil company drilling in China, leaves his bride-to-be to head for the Orient and straighten out problems at the inland-concession site his company controls. Chet Eaton, Johnny's brother and in-charge of the China operation, is drinking too much, plus a local Tartar bandit, Ho-Fing, is raiding and sabotaging the operation, having been bribed by a rival company. Johnny bribes him also but Ho-Fing is a what-have-you-done-for-me-lately guy and doesn't stay re-bribed. Johnny decides hand-grenades speak louder than money, and have a longer-lasting effect on Oriental bandits.
