The picture opens with the District Attorney (Alejandro Polledo), listening to voices from a recording in the black box retrieved from an air disaster.
The docudrama then tells the story of director Enrique Pi?eyro, who plays himself as T, a principled pilot at LAPA, an Argentine airline, upset over his company's disregard of basic safety regulations in order to save money.
When T complains, he's labeled a troublemaker by the airline company. Soon he's chastised by his fellow pilots. When things get worse he walks out of the cockpit after multiple navigational instruments are inoperative and refuses to fly.
The company simply replaces him and gets another pilot to fly.
Increasingly frustrated and worried about a crash, T finally writes an angry letter to his superiors, warning that a crash is inevitable if action isn't taken.
The letter is leaked to the media, and the airline is sold, but the new owners want Pineyro to retract his statement. Complicating matters, their public relations person is Marcela (Mercedes Mor?n), a love interest from his youth.
Even though Marcela is married, T pursues her.
T's story is inter-cut with the District Attorney who is looking into the LAPA flight 3142 crash, and starts receiving death threats.
Polledo's character manages to bring the company’s chief executives and the Argentine Air Force authorities before a criminal court, establishing a unique precedent in commercial aviation history.
