«18% Gray» by Zachary Karabashliev

After Stella disappears, Zack sets off on a trip across America with his memories, a camera, and a duffle bag of dope. Through the lens of the old camera, he starts rediscovering himself by photographing an America we rarely see. His journey unleashes a series of erratic, hilarious, and life-threatening events interspersed with flashbacks to his relationship with Stella.
