While Wayne works on controlling the cloning of himself, one of his new selves takes his place at work, where Bianca becomes suspicious of his geniality. Wayne is down because his clone is doing better than the real him. She gives his clone a friendship bracelet that is a tracking device, she befriends the clone and then uses him to kidnap Wayne.

Wayne's invention succeeds in finding gold - a pot of doubloons claimed by a leprechaun, who puts a curse on the Szalinskis until they hand it over.

To return from a time trip to 1864 Colorado, the Szalinskis must help an alien recover his starship from a ruthless gang, who master the alien's weapons and defenses.
