Two Argentinian citizens, in short soujorn in today's Havana, meet two local Cubans, who happen to be mother and son. Accidentally, one of the couples reunite after many years, and their fate changes drastically. The other couple, a case of platonic love at first sight, falls deeply in love in the backdrop of Cuba's famous sea wall: El Malecón. Finally, as a nice touch to the story line, the experiences of a homosexual couple and of a young heterosexual couple serve as secondary support to the plot.
