The Reminiscence Machine, which consists of a wireless helmet, water tank, holograms and a drug, is a system that allows a person to relive any memory they desire. The Reminiscence machine emanates from the war fought because of climate change. Nick Bannister served in the Navy but he was drafted for Border Patrol, where he worked as an interrogator. The Reminiscence machine originated as government technology that Nick used to interrogate prisoners by delving into their memories. However, after the war, being able to live in the past and experience your happiest memories repeatedly became something people were willing to pay for as a temporary escape from the harsh realities of post-apocalyptic nightlife in Miami. Somehow, Nick acquired the Reminiscence machine and set up a business in Miami's Spill-Zone, Bannister and Associate, that allows Nick to charge his clients by the hour to relive their most cherished memories.
