Martina is an Argentine singer who used to be famous during the late 90s and that today no one remembers. Among frigidness and love disenchantment, she's getting close to her forties. The arrival of a young Chilean couple will change everything: Francisca, a fan who's convinced they're sisters; and César, who with one look brings back her sexual desire. Martina will travel to Chile with the idea that César can give her back her libido, but she'll end up finding the affection of a possible new family.
