High atop one of Spain's poshest penthouses, three women have come to the end of their mental ropes. Super-sexy Pepa (Carmen Maura), is forever teetering around atop her skyscraper spikes, obsessed by Ivan (Fernando Guillen) the lover who just jilted her over the answering machine! Her neurotic best friend Candela (Maria Barranco), is seeking refuge at Pepa's place because she recently realised her lover is a Shiite Terrorist. And Ivan's ex-wife Lucia (Julieta Serrano), was just released from a 20-year stint in a mental institution. They're all mighty mad - in fact they're on the verge of a nervous breakdown... and one of them is about to commit murder unless the other half-crazed femmes fatales can stop her!
