The unscrupulous studio owner split a studio into two halves and rented it to two crews for filming. One group shot action special effects scenes, and the other group shot ghost movies. The director of the special effects scene, Quan Yuzhou, was informed of the breakup by his girlfriend on the first day of filming. He couldn't find the state of filming for a while and lost himself. Just when he was most helpless, Mou Tong, the heroine stand-in of the ghost film crew, took the initiative to persuade him. The two gave each other short but warm comfort during the ten days of filming. Because of some frequent situations in the studio and the crew, many hilarious plots occurred during the period. Just when the two were about to break up, the director finally called for the filming to be completed. It turned out that the producer wanted to reduce the budget of an action movie and a thriller that they had planned due to insufficient funds. Just when the two films were facing the crisis of stopping production, the director proposed a plan to merge the two films into a love story movie between the director and the female stand-in, called "The Brightest Star in the Universe".
