Four ambitious and beautiful young women. From four very different corners of Mexico. Just like hundreds of others, they are caught up in the frenzy that sweeps the nation when Alejandro Mateos, one of the country's most powerful producers, dreams up a nationwide talent search to cast the lead in his next big movie. But all this is news to Alejandro's on-again, off-again lover, Eva Gallardo, a diva of epic proportions, who expected to get the part. While Eva schemes to nail down the role, our four leads begin their own journey on the road to fame.

The story of a naive young man, provincial and not very experienced, to whom the circumstances of destiny, when crossing with the beautiful Frida, lead him to mature with a single blow. Rodolfo helps Frida in a car accident while she orders him to deliver an envelope. There begins the desperate flight of this innocent man fighting for his life, persecuted by thugs -who want to recover the contents of the envelope- and by the police -who seeks him for being a suspect in the death of an important diplomat.

A couple meet each other often in a motel room.

Composed of eight stories with comic overtones, all share the central theme of "love" and the extremes to which people will go to achieve it: unrequited love, deception and lust. They all offer a different take on the most difficult of human emotions: love.

At 18, fresh from high school, Marina, Ignacio, Adam and Mimi, school mates bonded by fate, shared a dream about adult life, a dream of fame, success, perfect skin and that one endless, true love that, surely, was waiting just around the corner for each one of them. But 30's arrived, and none of the sweet promises of youth was fulfilled. Alone, failed and frustrated, all four are forced to stop and look around to try to understand where it all went wrong, and find an emergency fix for their lives, before it's too late, and happiness escapes through their fingers forever. Secondary Effects is the bitter coming of age comedy that follows their steps in the search for lost dreams, lost hair and good sex, at least, if true love turns out to be a mirage.
