Tom (Sasha Roiz) is a scientist with a super high IQ who invented a technology that can extract the memories of others. The police applied this technology to the interrogation of prisoners. With the help of all parties, Tom entered the memory of a man named Anthony (Dominic Bogart). He was charged with first-degree murder. Tom's task was to find evidence that could convict him. However, an accident occurred during the experiment, and Tom was unable to leave Anthony's memory. In this way, he was trapped for four years. During these long four years, Tom and Anthony gradually became familiar with each other, and the latter finally agreed to put Tom back into reality, but there was an exchange condition, that is, Tom must help him investigate the truth of the case.
