Ye Shuangben is a calm and capable urban psychological counselor. With his ability to glimpse into the parallel lives of others through touching objects, he is unstoppable in the industry. However, during an ordinary consultation, she touched a client's pendant and witnessed herself transforming into a serial killer in a parallel world, committing numerous murders. In order to prevent reality from repeating itself, she is forced to be involved in a secret conspiracy that spans time and space. Dealing with the handsome detective Zhou Yan and the mysterious antique dealer Han Mo, she not only has to find out the truth about the corruption of her "other self", but also faces the moral dilemma of whether to intervene in parallel time and space. When her best friend is kidnapped and trust collapses, she must make a choice between saving the innocent, protecting herself, and maintaining the stability of time and space—and every choice she makes may trigger a butterfly effect and detonate the crisis of destruction in the multidimensional world.
