Dario Lizardi's life moves as randomly as the rollers of Ailén, his slot machine. Everything he lost during his 35 years of gambling addiction wasn't enough to take him off his obsession. Convinced that luck must be worked, that the most you know your slot machine, the closest you are to luck, Darío dreams of the day Ailén will give him back everything he gave. For that to happen, all he needs is to get a coin, pull the lever and make the rollers roll once again.
