Junto con "Divorcio en Montevideo" y "Luna de miel en Río", "Casamiento en Buenos Aires" forma una de las entrañables trilogías de Manuel Romero. Buena cantidad de enredos, infidelidades y final feliz.
A single mother who is denied work to support the son she had with the aristocrat who had seduced her, is helped by a singer, a director of orchestra and an American female singer, who get her shelter in the humble pension where they live.
