Voir Sadisflix. Wanderlust refers to the desire to wander, to explore the world, be free, and feel like a stranger in your surroundings. When the wanderlust takes over you, you know that the adventure has begun, but not where or when it ends. And how do you make a documentary without an end? This is one of the questions that directors Cristiana Pecci and Matteo Maggi ponder on his film The Fifth Sun.
