Land and Shade (2015)

Alfonso is an old farmer who has returned home to tend to his son, who is gravely ill. He rediscovers his old house, where the woman who was once his wife still lives, with his daughter-in-law and grandson. The landscape that awaits him resembles a wasteland. Vast sugar cane plantations surround the house, producing perpetual clouds of ash. 17 years after abandoning them, Alfonso tries to fit back in and save his family.
