It is said that a picture is worth a thousand words. In this case, it holds an infinite amount of secrets. These are secrets that only Cheng Xiaoshi and Lu Guang are able to find. In a small shop called "Time Photo Studio," the two friends provide a special service: using their extraordinary powers that let them enter photographs, they jump into pictures brought to them by clients in order to grant their wishes. Through the eyes of the photographer, they live through the events surrounding the picture and try to decipher how to solve their client's request. But every time they jump into a picture, they take a great risk. One wrong move and they could alter the future of the person who took the picture... and possibly countless other events too. So when the events they are forced to live through in these pictures start to become personal, it will take the utmost strength to push their feelings aside and focus on accomplishing the task they were paid to do.

The attempt to capture the mysterious perpetrator who possesses people ends tragically: Lu Guang is rushed to the hospital in a critical state, while Cheng Xiaoshi is arrested for the alleged crime. In light of recent events, the father of Liu Min unleashes his skilled, ruthless lawyer—Qian Jin—after Police Chief Li Xiao, who is spearheading the investigation related to the photo studio owned by Qiao Ling. It appears that no one is safe from the unpredictable and fatal attacks of the adversary who painstakingly hides their identity. As he tries to learn from his past mistakes, Cheng Xiaoshi must act swiftly and decisively to put an end to this devastating trail of death.

At the Time Photo Studio, partners Lu Guang and Cheng Xiaoshi accept jobs of a peculiar nature. With the aid of their complementary abilities, they are able to leap into photographs—thereby entering the past. One such case involves Liu Siwen, whose only wish is to marry his one true love, Ou Yang. However, her martial arts master father is apprehensive of a suitor who is an outsider and refuses to give his permission unless Liu Siwen defeats him in an honest duel. After years of trying and failing miserably because of his less-than-impressive skills, Liu Siwen finds himself seeking the help of Lu Guang and Cheng Xiaoshi. The two hatch a plan to outwit Ou Yang's father, but what seems simple in theory is rarely as easy to execute in reality…
