The Other Side of the Bed

“If love is only a game...Why not cheat?”

Paula has left Pedro (Guillermo Toledo), and he can't stop looking for the man who replaced him, hiring a private detective to find out. What he doesn't know is that his best friend Javier (Ernesto Alterio) is the one sleeping with her, and that Sonia (Paz Vega), the friend he leans on for comfort, has her own secrets. Emilio Martínez Lázaro lets the cast break into song, so the betrayals arrive as musical numbers.
