The film is inspired by the Qing dynasty painting Syzygy of the Sun, Moon, and the Five Planets by artist Xu Yang. The Director of the Imperial Observatory predicts that the sun, the moon, and the five planets will line up at noon on the first day of the lunar year - an event known as a “syzygy.” Officials worry that the prediction might not come true, so planetary deity Kuixing volunteers to contact the five planets to ensure the smooth alignment of the stars. At the same time, five treasures escape from the NPM and take off for the planets. Kuixing summons the Guardians of the NPM, consisting of the 15th-century Vietnamese Monkey King, Western Han dynasty Pottery Pig, and Tang dynasty Madam Tang (Pottery Figure of Lady Playing Polo) to help search for the five escaped treasures and restore peace and prosperity to the universe.
