As the man, who goes by the name "Walker" due to his condition, attempts to piece together his identity, he discovers that he has a set of unique abilities. Each time he wakes up in a new body, he is able to access the memories and skills of that individual, making him a valuable asset to those who know about his condition.
The woman who claims to recognize him, a scientist named Dr. Reyes, reveals to Walker that he was part of an experimental program aimed at transferring consciousness between bodies. However, due to a malfunction, Walker's consciousness became stuck in a cycle of switching bodies every 12 hours.
As Walker delves deeper into his past, he realizes that the organization chasing him is actually the ones responsible for his condition. They want to exploit his abilities for their own gain, but Walker refuses to be a pawn in their game.
With the help of Dr. Reyes and a hacker named Max, Walker sets out to find a way to break the cycle and return to his original body. However, as he uncovers more about his past, he realizes that the answer may not be as simple as he thought.
As the clock ticks down on each 12-hour cycle, and the organization closes in on him, Walker must use all of his skills and the memories of his hosts to stay alive and unravel the mystery of his own identity.
