By the time she is 14, she has already had two children by her father Alphonso "James" Harris (Leonard Jackson). He takes them away from her at childbirth and forces the young Celie (Desreta Jackson) to marry a wealthy young local widower Albert Johnson, known to her only as "Mister" (Danny Glover), who treats her like a slave. Albert makes her clean up his disorderly household and take care of his unruly children. Albert beats and rapes her often, intimidating Celie into submission and near silence. Celie's sister Nettie (Akosua Busia) comes to live with them, and there is a brief period of happiness as the sisters spend time together and Nettie begins to teach Celie how to read. This is short-lived; after Nettie refuses Albert's predatory affections once too often, he kicks her out. Before being run off by Albert, Nettie promises to write to Celie saying, "Nothing but death can keep me from it!".

A mischievous Elliott makes himself visible, and a terrified Lampie runs into the saloon to warn the townsfolk ("I Saw a Dragon"). In a seaside cave, Pete scolds Elliott for causing trouble. Just as they make up, Lampie's daughter Nora appears, having spotted Pete earlier. She says that due to the ongoing tides from the sea, that it's unsafe for Pete to stay, thus leaving Elliott to remain there.

The film opens with the tail end of a Friday night baseball game. With the bases loaded, the home team wins by a narrow margin as the batter hits the ball out of the park. Both the celebration of the home team and fans and the dread of losing for the visiting team are cut short as a mysterious spaceship floats over the park, thus snatching the attention of everybody there: the players, the fans, the hot dog and popcorn vendors, and the announcer. After the ship performs a tune, it dissipates into three floating balls of light. One of them forms into a ghost who initially appears as an alien, but thereafter, is revealed to be Fatso (voiced by Jess Harnell), a member of The Ghostly Trio, who releases gas which hits the scoreboard, causing it to explode, also sparking terror. The other two ghosts of the trio, Stinky (voiced by Bill Farmer), and Stretch (voiced by Jim Ward), join in, causing panic in the park, as everybody got frightened. Casper (voiced by Jeremy Foley), a shy, friendly ghost (whom all three ghosts are uncles to), arrives, attempting to settle the frightened crowd, but the people are just as scared, saying that Casper's a ghost and ran away. The park is eventually empty, as Casper's uncles plan a vacation.
