Mateo and Rufus meet through Last Friend and decide to spend the day accompanying each other. Rufus flees and goes on the run, downloading Last Friend so that he won't live out his final day alone. Rufus, Aimee, Malcolm and Tagoe, collectively known as The Plutos, hold a funeral for Rufus at his foster home but it is interrupted by Peck, who calls the police to have Rufus arrested for assault. He allows Peck to leave so that he can return to his foster home to say his goodbyes.

His friends Malcolm and Tagoe remind Rufus not to get carried away because of the news. Rufus is in the middle of beating up Peck, his ex-girlfriend Aimee's new boyfriend, when he received a call from Death-Cast claiming he is going to die in the next 24 hours.

Mateo initially intends to spend his End Day in his bedroom but decides to try to push himself to truly live, reluctantly downloading Last Friend, an app developed to help lonely Deckers find someone to spend their End Day with. Shortly after midnight on September 5, 2017, Mateo receives a phone call from Death-Cast, a company that rose to prominence seven years prior and is able to predict the deaths of individuals, informing him that he is now a Decker, someone with only twenty-four hours (or less) left to live.
