S.O.S. Ex.

El Chino Fernando and el Puma, two old friends who have not seen each other for some time, go out with their ex-girlfriends for a sailing trip. As a reminder of their "ex" status, differences soon surface and they decide to end the ride early. However, on the way back they are surprised by a storm that throws them off course, leaving them adrift in the middle of the widest river in the world.
