Yo, tú y ella

In Paris, on New Year's Eve, Estrella and Gabriel Villalba and Estrella's sister Fernanda prepare for the evening's festivities. At the last minute, Gabriel informs Estrella that he will be unable to accompany her. After seeing his lover Laura, Gabriel informs Estrella that he must leave to attend to business in Biarritz. Acting on her intuition, Estrella accuses Gabriel of seeing another woman. Gabriel confesses to the affair, and after Estrella proclaims them finished, he leaves. Later, Estrella accompanies Fernanda and her new husband Carlos on their honeymoon. When they arrive in Venice, Estrella notices that Gabriel is staying at the same hotel with his new wife Laura, whom Estrella has never met. Laura, who is spoiled and ungrateful, fights with Gabriel. Seeing Estrella sitting alone by the pool, Laura, captivated by her elegance, tries to start a conversation with her; however, when she sees Gabriel on the diving board, Estrella abruptly leaves. Later that day, Laura sees Estrella at an outdoor café, and Estrella, not knowing that Laura is Gabriel's wife, agrees to join her. When Laura introduces Gabriel as her husband, Estrella's initial shock turns to glee. Calling herself a widow, she proceeds to take potshots at Gabriel's expense with ammunition supplied by his unknowing new bride. The couple leaves after Laura flirts with one of the restaurant's musicians, and in their room, Laura accuses Gabriel of being attracted to Estrella. She follows him to Estrella's room, and after he walks out in anger, Estrella reveals the truth about their previous marriage to Laura, who is aghast. Estrella, Fernanda and Carlos then travel throughout Europe pursued by telegrams from Gabriel, who wishes to talk with Estrella. After they finally reach their home in Madrid, Gabriel arrives at Estrella's house, while she prepares to leave for an engagement which, she hints, involves another man. Laura then phones him, and their ensuing argument ends with his promise to leave her forever. He goes to seek advice from a mutual friend of his and Estrella's during which time Estrella returns and retires to her bedroom. Gabriel then returns and pushes his way past the maid into Estrella's room, where he asks her to come back to him. Estrella asks him to leave, but when he refuses, she goes out followed by Gabriel, who continues to plead with her. Without a taxi in sight, Estrella enters a movie theater, and as the onscreen lovers argue about their relationship, Gabriel promises her that he will be a new man. Estrella replies that she only desires the man with whom she once fell in love. As the onscreen picture ends, Gabriel and Estrella embrace, and as the theater patrons file out, they pass the coming attraction which reads: "Don't Trust Your Husband."
