The Dukes of India

Boss has his buddy, the Grand Vazir, set up traps to slow down the Dukes. The Grand Vazir is trying to keep his nephew, Prince Ahmed, from coming to his corination ceremony. That way, the Grand Vazir can claim the throne. Turns out, Vance is a dead ringer for Prince Ahmed. So when he is caught instead of the Prince, the Dukes and Ahmed have to free him and claim the throne.
