Song Shi'an, who died suddenly from staying up late, transmigrates into an extra actor burdened with 180,000 in debt and binds with the "Extra Acting System". By playing one hundred extras fully, he can exchange them for ten billion in assets and a long life. He goes wild with joy—acting as an extra is easy, the pay is enough to spend, nobody is watching him closely, perfect! As a result, every time he plays an extra, he becomes a hit, with the entire internet crying and begging directors "not to knife him". His manager chases after him to feed him male lead scripts, but he only wants to hide in the crew to play corpses that die early and get off work. The less he wants to be famous, the more ridiculously famous he gets. The system forces him to be a top traffic star, but he just wants to lie flat—this funny battle of "being made a top star" officially begins.
