'Perhaps that moment had been exceptional, but still, I felt alive. That pressure on my chest means being alive.' Forty-nine, with a kind face, no serious ailments (apart from varicose veins on his ankles), a good salary and three moody children, widowed accountant Martin Santome is about to retire. He assumes he'll take up gardening, or the guitar, or whatever retired people do. What he least expects is to fall passionately in love with his shy young employee Laura Avellaneda. As they embark upon an affair, happy and irresponsible, Martin begins to feel the weight of his quiet existence lift - until, out of nowhere, their joy is cut short.
