　　The film tells of how street sweeper Alonso (played by Roberto Álamo) and tarot reader Marisa (Malena Alterio), the proprietors of a delicatessen Torres and Fátima (Jordi Sánchez and María Botto), plastic surgeon Calatrava (Julián López) and influencer Vicky (Kira Miró) have booked a house in the middle of nowhere on the Canary Islands, where they hope to spend the best holidays of their lives with their respective broods.
　　What they don’t know is that, because of a mistake made by the travel agency they used, they have all rented the same house. And none of them is willing to back out, although there is not much of an alternative anyway, which means that they will be forced to share the same living space for the whole of the summer. The glaring differences between each and every one of the occupants will turn these days into a chaotic series of entertaining and messed-up situations. Despite this whole disaster, they have to learn how to live together and how to understand all of these wildly different people – and, above all else, themselves.
