Lolas a single mom, broke, working as a janitor and maid. Silvia is pregnant, and her lover (her boss) wont leave his wife. Maite, newly a widow, discovers shes 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: theyll use replica guns, dress as men, take Silvia hostage, and all will be smooth. But things go awry, including the fact that Lolas ex, Gustavo, is a cop. Desperation may be the mother of invention - and a corrupt bank manager its father.
