In this short (and sad) documentary about seafarers, we get to see our world from a different perspective. Quoting from the article that accompanies the video:

The international shipping trade depends entirely on these guys, but they have very few rights and freedoms in the places they stop at during their long journeys working far from home. It is thanks to the Seafarers association and its volunteers, which run the center, that they have anywhere to go at all.
