A baby is born and nobody knows who his father is. About ten months ago, Nicolás (Rosalía Valdés) was in a desperate situation because her boyfriend Jorge (Fernando Balzaretti) resisted her advances to get intimate by reason it would undermine her parent's trust. As a conservative man with a traditional view on relationships, he thinks it will be better to marry first.
In her free time, Nicolás works as a model, posing nude before the lens to pay for her college and mitigate the burden on her struggling veterinarian father, Don Ramón (Guillermo Orea), whose pastime of preference when he is not helping animals is looking at magazines where minimalistic attires are favored. In one of her shootings where the theme is Adam & Eve, Nicolás meets Paco (José Alonso), a political activist student with progressive leanings, and the two become infatuated after her intentions are responded to her liking.
One of those magazines reaches cinematographer Hugo Valdemar (Pedro Armendáriz Jr.), who, upon seeing the images of naked Nicolás, cannot believe his eyes, and her alluring silhouette will beckon him like a forbidden fruit asking to be reached and touched.
Directed by Julián Pastor and co-written with Juan Prosper, El vuelo de la cigüeña explores the misadventures of Nicolás trying to find love with three different candidates. Three lovers who differ in many ways, from an economic point of view to their ideological leanings. The movie illustrates her search for love in a humorous fashion where its comedy consists mostly of character and physical comedy. It has erotic elements by reason of its protagonist and the scenes where she is undressed in photoshoots. And even though Rosalía Valdés is a delight to see, it is in this last aspect that the movie's self-indulgences are found, considering they make the pacing uneven sometimes.
One of the most interesting aspects of the movie is that it touches, if only slightly, female sexuality and how the same situation is looked at with different eyes by society. Nicolás having a three-way relationship naturally illustrates a polyamorous examination of her sexuality but also how it can be an emancipatory medium to be free of patriarchal authority.
