Mickey and the gang are having a masquerade Halloween party outside the Tower of Terror. After the party starts, two cast member hosts warn the guests not to touch the cursed ancient artifacts that surround them. Wanting to prove he's not scared and that curses don't exist, Donald Duck takes a spear from a Tribal Mask. After a tense moment, nothing seems to happen and the party goes on. Everyone is relieved and they continue dancing and having a good time.
However, while everyone is partying, the Tribal Mask comes to life and starts chasing Donald, eventually cornering him on the balcony. Mickey and the gang look up just in time to see the cursed artifacts take Donald and sink through the floor. Donald soon rises up again, now possessed by the spirits and believing he is a savage himself. One by one the gang is taken over; Daisy becomes an Aztec goddess, Goofy becomes a ruthless pirate from Davey Jones' locker, Chip and Dale become Chinese ghosts, and Minnie becomes an evil Egyptian Queen. During their possession they have no memory of who they used to be, as shown when Minnie passes Mickey aside, thinking he is nothing more than a petty commoner.

It's Halloween Night, the only night Ghosts can come out to play. He agrees to party with them, but "Only for Tonight". After the ghosts possessing his friends have their fun they depart from their hosts, as they've had their fun and have to run off now, before the sun breaks.
