Benjamin Ballon wants to be a filmmaker, and has devoted a large part of his life for the past few years to getting to the point of filming an independent movie. He has been encouraged by Carmen Maura (playing herself), an established star, who has agreed to appear in his first film, and it is her level-headedness, calmness, and general good sense that keeps the project moving along, despite Benjamin's inexperience and a very temperamental male lead. On one occasion when the male lead is hours late for a shoot, her calm is the only thing which keeps the crew from walking out. The title comes from Maura's habit of bringing homemade tortillas to meetings, and using them to get her way.

Ariane and Hugo decide to exchange the lives they lead to escape from their routine, which after ten years of marriage, gives them the feeling of being hamsters in a wheel. She suddenly finds herself at the head of a construction equipment rental company and he tries to take the role of a house calling jewelry salesman...But is life really better when you live it on the other side of the bed?
