Clara Montsalvatjes inherits an enormous apartment in the centre of Barcelona and decides to turn it into a space where she can take care of female friends going through a rough patch, be this related to work, romance or their health. Summer arrives, the space becomes empty and a couple of mysterious neighbours move into the flat opposite and lose no time getting stuck into unpleasant shouting matches. Partly due to fear of violence and partly for fun, Clara invites her old boyfriend round to help her 'resolve' the situation while they decide what the future holds for them. After a night of laughter interrupted by blows and yelling, Clara ends up breaking into the flat opposite and (spurred on by curiosity and in spite of her common sense) becoming the confidante of her female neighbour, who will drag her into a whirlpool of adventures where modest origins mingle with the promise of luxury.
