While Astrid is getting ready for her senior prom, Lydia dies from a prop malfunction on her show, and Beetlejuice thinks that maybe she'll finally be his bride. Astrid accesses the Neither-world to save her mother, while Lydia and Beetlejuice are being hunted down by the vengeful souls of those Beetlejuice wronged in the past. Overtime, BJ learns to clean up his act (for real this time), especially with his assistant, Bob, and his new pet Sandworm to help him and Lydia.
