In an unnamed city, colonised by an unnamed world power, an immigrant named Gastón makes his living selling exotic vegetables to eateries around the city. He has a dog called Kitten, who's been diagnosed with terminal cancer, and a good friend called Max, who's in a deep depression after being forced to close his restaurant. Meanwhile, Max's son, Pol, a scientist away on a scientific expedition into the Arctic, can offer little support.
Gastón begins a quest, or rather three: he must search for someone to put his dog to sleep humanely; he must find a space in which to open a new restaurant with Max; and he must look into the truth behind the news being sent back by Pol: that human life may be the by-product of an ancient alien attempt at colonisation . . . and those aliens might intend to make a return visit.
