Guo Xiaojing, a simple and cute puppy killer, is nicknamed "Little White Rabbit" in the industry - because he always smiles and says softly "Don't be afraid, it won't hurt" when killing people. But no one knows that every time he performs a mission, he triggers a strange ability: traveling back in time.
During a mission, Guo Xiaojing encountered Wang Dali, a stupid thief who was stealing something. This fool could get himself stuck in a window while stealing things, hanging upside down and still giggling. What's even more outrageous is that Wang Dali accidentally took away Guo Xiaojing's important prop - a mysterious pocket watch that can trigger the reversal of time.
From then on, the fate of the two living treasures was entangled. Guo Xiaojing wants to retrieve the pocket watch, while Wang Dali wants to learn to "reverse time" to steal more treasures. But every time you get closer to the truth, a deeper conspiracy emerges. A mysterious killer organization, a madman who wants to rule the underground world, and a mastermind who can control time...
The innocent and kind-hearted milk dog killer met the cutely stupid thief. The two escaped from death again and again in the maze of time travel, and uncovered bigger mysteries again and again. And when Guo Xiaojing finally discovered that his "ability" was actually part of a huge conspiracy, it was too late...
