This Mexican sex-comedy centers on Eruviel (César Manjarrez), a mature man whose sudden struggle with sexual impotence completely disrupts his marriage to his beautiful, much younger wife, Dionisia (Andrea Portugal). Desperate to keep the flame of passion alive and maintain their dream relationship, Dionisia attempts a thousand and one increasingly chaotic and outrageous methods to revive their love life, while Eruviel tries his own desperate counter-measures. However, as domestic frustrations boil over and her husband's attempts fall short, the boundaries inside the household completely fracture when Dionisia turns to her attractive stepson, Jimeno (David Eduardo), for the attention and physical fulfillment she craves, sparking a highly transgressive affair right under Eruviel's nose.
