Venice: a man and a stranger wearing a mask erroneously exchange their suitcases. A quick and furtive meeting is enough. Everything starts (or it might even be the end!) in quest of a formula whose effects are miraculous and which has been worked out by a biologist now hidden somewhere in the Venezuelan paradise.

The first getting in his/her hands the precious formula will become rich, very rich..
