Watch David Beckham: Into the Unknown

After 22 years of playing for the world's greatest football teams, David Beckham has retired and he has the freedom to do whatever he wants. To mark the occasion he's going on an adventure. He's chosen Brazil, and he's taking 3 of his closest friends to join him on this once in a lifetime experience. Starting with a beach foot-volleyball game in Rio, they travel deep into the Amazon, ending up with the remote Yanonami tribe, with David desperately trying to explain the beautiful game.
