A simsense company has developed a new kind of simsense chip: one which transforms the user's personality to that encoded on the chip. The three prototypes (Cleopatra, Ghengis Kahn, and Jack the Ripper) have been stolen, and the PCs are hired to go and get them within a week. This brings them in situations ranging from a gang war to a simsense company party to the back alleys of Redmond.
