The 6th Day

In the near future, cloning technology is highly developed and the corporation Replacement Technologies owned by the wealthy Michael Drucker is responsible for cloning pets in RePet shops. However there is a law called Sixth Day that prohibits human cloning and many groups and movements that are against any type of cloning. When Drucker needs to travel to a remote location, he hires the professional helicopter pilots Adam Gibson and his friend Hank Morgan, requesting an eye test from them first. However Hamk flies since it is Adam's birthday; the family dog has just died and he is thinking about the possibility of cloning the animal for his daughter. Adam decides to by a doll called Cindy instead but when he arrives home, he finds that Olive and him have been cloned. Further, he is hunted down by four professional killers and he needs to flee. What happened to Adam and why was he cloned?
