Amazon has released the trailer for Human Flow, a documentary directed by world-renowned artist Ai Weiwei, that looks at the global refugee crisis. The film will be released in theaters on October 13.

Captured over the course of an eventful year in 23 countries, the film follows a chain of urgent human stories that stretches across the globe in countries including Afghanistan, Bangladesh, France, Greece, Germany, Iraq, Israel, Italy, Kenya, Mexico, and Turkey. Human Flow is a witness to its subjects and their desperate search for safety, shelter and justice: from teeming refugee camps to perilous ocean crossings to barbed-wire borders; from dislocation and disillusionment to courage, endurance and adaptation; from the haunting lure of lives left behind to the unknown potential of the future. This visceral work of cinema is a testament to the unassailable human spirit and poses one of the questions that will define this century: Will our global society emerge from fear, isolation, and self-interest and choose a path of openness, freedom, and respect for humanity?
