A prety story unfolding on the fantastic and tropical island "Bomgo-Bomgo".

Alan (Terence Hill) is a trouble maker. He spent all his money and loan money from Maffia in the horse racing. He visits his uncle Brady, but he don't advance money because of a lack of trust on Alan. However the uncle delivered a map of hidden treasure of Bomgo-Bomgo island. Now Alan refuged in a boat for running away from Maffia... The captain of the boat is Charlie (Bud Spencer) who just started to cruise all around of the world. If he makes it by only himself, he will get a big prize from his sponsor. But he finds a stranger who eats every lunch of him. Charlie catches up Alan, and they satart fighting on the deck. At last they missed their step, and droped into the middle of sea...

Alan and Charlie found their way to Bomgo-Bomgo island. There is a happy tribe with their leader Anulu (Sal Borgese) who is born between a mother as Queen of the tribe and a japanese father. Anulu's father is a soldier who keeps hiding in the island 30 or 40 years even after 2nd world war finished. And he still believe the war continue... Finally Alan knows the treasure is hidden under the ground of this soldier's fort. Alan and Charlie decide to go the fort with the help of Anulu.

I'm always happy to just watching Bud+Terence naturally, but this film is not well conduct their charm. It's a really rare case of master Sergio Corbucci. Undoubtedly he had not enough time to directing. The film little bit drags out, and I've an impression that the personality of Charlie and Alan is not enough established beside the other personalities incarnated by Bud+Terence.

But there is several good elements. For exemple, the presence of Sal Borgese is specially important. Anulu is unimaginable. He says haphazard words and struggling anytime, at last he gets a someone's slap on his head ! Sal Borgese is one of the actors who makes me happy, in Gianfranco Parolini and of course Bud+Terence films.

And a japanese solidier (like Mister Yokoi who had stayed in Guam during 27 years after the war) is amazing ! I think the actor is half Japanese and half American, but he doesn't say any japanese words without Ban-Zai. Nevertheless I was very happy to hear Terence Hill's Ban-Zai and to that Bud Spencer didn't let him do Harakiri. The relation of Alan and Charlie with Anulu and Japanese soldier is interesting and the film is not boring at all.The story is relatively steady, so I wanted just a little more action.
