In Gijón Principality of Asturias (northern Spain) Santi is a down-on-his-luck 30-something who was fired a year ago from his factory job and Maite his wife of 9 years is filing for divorce. Now he lives in his van waiting for a job that never comes and passes his days with his best friends Marcos--happily-married father-of-two--and Pedro a single gas-station worker who lives with his mother and dreams of being a ladies' man. Trying to have a moment of peace Santi and friends go to a class reunion and discover that former classmate Mario is now successful--and Maite's new boss in the supermarket Todoymás (Allandmore) where she works. After a bitter visit to the lawyers with Maite to regularize the divorce Santi decides to buy a lotto ticket as a last hope to change his luck. The next day a surprised Santi learns on the radio that the ticket has been prized with 25 million EUR (27 million dollars) and goes to the bank to take the money but fearing to be exposed to the public eye he runs from the bank. However bank manager Damián approaches Santi to advise about how to manage the 25 millions where Santi discovers unwelcome news: due to the conditions of his and Maite's marriage she has a right to half the prize. Unwilling to lose 12.5 millions to her he starts to spend the money in secret enjoying all kinds of luxuries while openly pretending to be poor. In an act of goodwill Maite gets Santi an interview with Mario for a stockman job. Santi uses part of his money trying to better the lives of Marcos and Pedro with disastrous consequences also failing in his attempts to reconcile with Maite. Then by chance Santi finds out about Mario's real intentions with Todoymás. Can Santi fix all the troubles that the money caused before it's too late?
