Coyame, Mexico is a small town not far from the US border.
It's home to three thousand people and possibly the best-kept secret of all-time.
In August of 1974, the USA military was tracking a mysterious object over Mexico; then suddenly it disappeared from radar near Coyame.
At the same time a civilian plane headed in the opposite direction is reported missing.
What follows next is the stuff Hollywood blockbusters are made of: a crash site, a spacecraft, dead bodies, a covert recovery mission, and a government cover-up.
Is this the story of the century, or just a piece of Mexican folklore?
Over the last 15 years, Mexico has experienced an unprecedented UFO wave.
While the sheer volume of encounters garners attention, it's the apparent quality, or credibility, of these incidents that has our attention.
Through interviews with witnesses and experts we examine the evidence, and controversial footage released by the Mexican military reveals never before seen video.
