Data takes over control of the Enterprise, and takes the ship to his creator, Dr. Soong. This action endangers a child on Enterprise who must be quickly treated at a Starbase, or he will die from a deadly poison he ingested earlier.
Data is unaware of his actions until he meets his creator. Dr. Soong has called Data back to receive an emotion chip which will make him more human. However, in a strange twist, Lore turns up too, as he also had the recall program.
Lore finds it strange that his creator has not worked on a fix for him, and decides to take an action which will lead to great future repercussions for Data, and the crew.
