Was Columbus really the first to discover America? This searching documentary sets out on a voyage of rediscovery - and comes up with a remarkably convincing case for a revision of accepted history. Five hundred years ago three ships sailed from Spain on the most famous voyage in history - west, west and always west across the unknown ocean. But now a modern Spanish ship's officer and a journalist have re-created that momentous voyage to test their astonishing theory that Columbus not only knew where he was going but also what he would find in the not-so-New World.
