The Managers of the fabulous Hotel Casablanca in North Africa are dropping like flies.

Each is being murdered as he innocently blunders onto the stolen jewels and art treasures that a gang of escaped Nazis have stashed in the hotel. And so another Manager arrives.

Its Groucho. The zealous Chico, operator of the Yellow Camel Taxi Service, becomes the new Managers self-appointed bodyguard. Harpo becomes the mischievous valet to Sig Ruman, villainous leader of the Nazi gang.

In their last important film together, the Marx Brothers are pulled into one crazy situation after another.

The many plot twists put the boys through their hilarious paces, culminating in an outrageous chase scene resplendent with airplane (sic) acrobatics

The boys, as usual, save the day and the criminals are brought to justice.
