At some point in the indeterminate near future, the cloning of animals and human organs has become routine. Cloning entire humans, however, is prohibited by what are known as "Sixth Day" laws. Billionaire Michael Drucker, owner of cloning corporation Replacement Technologies, hires charter pilot Adam Gibson and partner Hank Morgan for a ski trip. Due to Drucker's prominence, the two must first undergo blood and eye tests to verify their aptitude. On the day of Drucker's arrival, Adam finds that his family dog Oliver has died, and Hank offers to fly Drucker instead to allow Adam time to have the pet cloned. After visiting a "RePet" shop, he remains unconvinced and purchases an animatronic doll, a SimPal, named Cindy instead (Voice by Andrea Libman).
