In Madrid, Azu's husband Filipe is smug and boorish, but it's his money she slips to family members constantly in need of cash and that she uses to buy gifts for her lover, Pablo. Things start to fall apart when Pablo wants to leave her and when Filipe wants to evict Azu's cousin from a butcher shop he rents. Azu hatches a plan that relies on her sister, her cousin the butcher, and his mentally-challenged delivery man. When things start to go wrong, can Azu make them right?

Azucena es una maruja psicópata que, harta de su marido Felipe y locamente enamorada de Pablo, su amante, decide eliminar a su marido de la ecuación y poner en marcha un plan para enviudar lo antes posible. En su paranoia asesina, Azucena recluta a Isabel, su apocada y dependiente hermana, a su primo Quique, un carnicero demasiado sensible, y a un recadista medio tonto llamado Lalo. El plan resulta una auténtica chapuza, pero Azucena descubre la adicción al crimen. A partir de ese momento, todo el que estorba será eliminado.
