The story of the monster prince and the dinosaur princess continues. Shrek thought he could live a free and easy life with Fiona in the swamp, but Fiona's father, the king of the "Far Away Kingdom" who turned into a frog, was seriously ill, so Shrek and Fiona had to give up their freedom and inherit the kingdom. For Shrek, "misfortunes never come alone": Fiona is pregnant, and he is obviously not ready to be a father. Because he doesn't want to inherit the kingdom and because of the upcoming little monster, Shrek takes the chatterbox donkey and the cat in boots to find Fiona's distant cousin Artie. After their soft and hard persuasion, the lazy Artie finally agreed to take over the throne, and the four of them began a lively journey back home. At the same time, Princess Fiona, who was accompanying her parents at home, also encountered considerable trouble. The big villain "Prince Charming" gathered a group of pirates to make a comeback and plot to usurp the throne. Fiona organized a women's self-rescue team. The princesses and queen mothers in fairy tales all came on stage and launched a hilarious battle for justice. Shrek and his four companions who arrived at the kingdom in time also joined the team, and the prelude to the "alternative" decisive battle began.
