Desperate to earn some extra money, student Ana (Ona Casamiquela) answers a job advert for a part-time nanny. Arriving at apartment 3B in the town square for the job interview, things couldn't have gone better - tea, biscuits, nursery rhymes and a healthy hourly rate. Before long, however, Ana realises she has entered a terrifying dark world of obsession and misery. Kept prisoner in a creepy residence full of antique toys, Ana must try and overcome deranged diva Diamantina (Luisa Gavasa) and her daughter Elisa (Ana Turpin) to prevent herself from becoming just another possession in the house of 1000 dolls.
