For some, the graveyard might be the final resting place for the dead, but for the men of Atan Cemetery in Lagos, Nigeria, it's where their work begins. In this documentary, "The Gravediggers," first-time directors Hassan Yahaya and Kayode Idowu speak with those who dig graves for the dead. Through their stories, we learn what it means to work graveyard shifts and how they take pride in their job, even when people look down on their means of livelihood.
