Despite Bob's efforts to disillusion Maria, the two quickly fall in love. With his plan gone awry, Acuña orders Bob to leave Buenos Aires, and composes a farewell love note on his behalf. Acuña's wife sees him writing the note at their 25th wedding anniversary party and accuses him of cheating on her with another Maria, her dear friend Maria Castro. Bob is forced to reveal the truth in front of Maria and the rest of the family. Impressed by Bob's behavior, Acuña grants him permission to court Maria. After repeated deliveries of flowers fail to accomplish anything, Bob dresses up in armor and rides in on a horse, imitating Lochinvar, a fictional knight Maria had adored when she was young. This does the trick. Maria finally forgives him.
