Four people are about to take part in a dangerous experiment. The rules are simple: if you want to live, you have to go to sleep.

Abril left Daniel behind 5 years ago, when she decided to try her luck in London. She is back home now, to bury her grandmother. Walking the streets of what was her home with the man who was her love, she realizes she had missed it all.

Lola's a single mom, broke, working as a janitor and maid. Silvia is pregnant, and her lover (her boss) won't leave his wife. Maite, newly a widow, discovers she's penniless but wants to maintain appearances and give her daughter a fancy wedding, and Pecholata, a punk kid living in a youth center, will soon be turned out on the streets. Lola, who cleans a bank every morning, decides to rob it, convincing the others to join her: they'll use replica guns, dress as men, take Silvia hostage, and all will be smooth. But things go awry, including the fact that Lola's ex, Gustavo, is a cop. Desperation may be the mother of invention - and a corrupt bank manager its father.
