Synopsis：Lizi is dedicated to researching memory-swapping technology, and her boyfriend Zhong Han is very supportive. Scientist Bai Tangwu secretly works on cloning humans but can only produce soulless shells. He realizes that memory-swapping technology is exactly what he needs. However, Lizi refuses to cooperate with Bai Tangwu. Bai Tangwu turns Zhong Han into an "idiot" to trick Lizi into helping restore his emotions. Zhong Han suddenly becomes a suspect in the kidnapping of anti-cloning expert Liu Daming. Lizi tries to clear Zhong Han's name, only to find Liu Daming's corpse in her own home. Bai Tangwu proposes cloning Liu Daming and implanting memories. Lizi reluctantly agrees. Sneaking into Bai Tangwu's lab, Lizi discovers the truth: the real Zhong Han is dead, and the current Zhong Han is Bai Tangwu's clone. Bai Tangwu is using the memory-swapping technology to mass-produce clone assassins. Lizi and Zhong Han team up to destroy Bai Tangwu's lab. As they flee, Zhong Han locks himself inside, perishing with the lab. Weeks later, Lizi finds out she is pregnant with Zhong Han's child, which gives her the strength to face the future.
