In 1973, a dozen misfits from seven countries embark on a seemingly impossible mission. Equipped with a 16mm film camera to document their adventures and led by the eccentric Spanish explorer Vital Aslar, who tells his crew to anticipate UFO encounters, they set out to cross the world’s largest ocean on the longest-ever-recorded raft journey, to prove that the South Pacific may have previously been colonised by South American mariners. For the next six months, the rafts attempt the 9,000-mile crossing from Ecuador to Australia, with only the sun and stars to guide them. In the unforgiving vastness of the Pacific, as food dwindles and each day brings them closer to psychological breakdown, they are forced to confront their deepest selves. Just as they appear on the brink of success, the mother of all storms leaves one raft and four men missing. What led this band of outsiders to attempt such a mad endeavour? And for those who live to tell that tale, how will it change them?
