Eva, ¿Qué Hace Ese Hombre en Tu Cama? plot
Manolo is a singer-composer obsessed with the pictures of a beautiful girl on a calendar she has signed by the name of Eva. He himself is engaged to Salome, who does everything in vain to get Eva out of his mind. At inappropriate hours he is composing his songs, and this causes frequent conflicts with his downstairs neighbors in the apartment building where he lives. One day, he learns that Eva's calendar is being used as an advertisement in a Puerto Rico hotel chain. He travels there and when he finally meets Eva in one of the hotels he discovers something he had not expected at all.
