Ten participants are about to start a race in which the most important thing is not to win, but to finish, in the race of their lives.
In a village in the Sierra de Madrid, a couple feels that their children, who have since moved out, have forgotten about them. To get them back, they will pretend that they have won the lottery and that they are multimillionaires.
A dysfunctional family gathers after receiving news that their millionaire grandfather is dying. Driven by greed, they hold a feast, only to discover that the old man has hidden away over a million euros. Amidst arguments fueled by the guests’ various delusions and phobias—and the simultaneous arrival of a group of incompetent mobsters also hunting for the loot—absolute chaos erupts.
