When Zigor, a mature man, a successful businessman and married to an aristocrat, finds himself facing a terminal illness, he decides to gather the seven members of the terrorist cell with whom he fought to overthrow the military regime that held power before the establishment of the Republic. The group of 'Willow Tree House' was dissolved after a failed attack: they have had nothing to do with each other since laying down their arms twenty years ago. But the years have not passed in vain for these eight people whose lives have been determined by their old struggle. Now, reunited once more, their remorse, guilt and resentment come to the surface with the devastating force of a torrent of water that has been contained over years, leading them to a purifying and necessary catharsis.
