" Otto Krause, the exemplary mailman, has never accepted the mysterious disappearance of his four-year-old daughter, Mary. Decades now passed, Otto, eighty-seven and demented, faces a rather unorthodox dilemma. He no longer knows if he is alive or dead. Sensing that if he waits much longer he might never know the truth, Otto launches a dramatic escape from the nursing home where he lives to return to his old postal route, now a down-at-the-heels Houston neighborhood. There Otto meets Ayana, a young Black girl on the run, her heart hardened by abuse. Despite Otto's unstable mind and nuclear grumpiness, a tender, immutable bond forms between them. While hiding out in a cold storage room, the two misfits decide to join forces. The next day they embark upon a remarkable odyssey. Ayana will help Otto find Mary and the old man will seek to do the impossible. Lead a broken, young girl to a life worth living. A life filled with safety, kindness, and love. "
