In a Post-Pandemic America, one of the only things still remotely functioning is the mail. But with mass casualties to their ranks, the postal service has been forced to adapt to a consistently more aggressive set of routes with fewer and fewer carriers to service them. One of the last remaining Postmasters, 32, sets out to deliver a one-of-a-kind letter that's mysteriously appeared at the Western States Distribution Center. Rugged terrain, highway robbers, and The Wicked all stand between 32 and his destination. But he knows the motto. Neither rain, nor sleet, nor dark of night will stay the swift and timely completion of his appointed rounds.
