Robots were infiltrating the Federation. Someone was kidnapping people and substituting indetectable, synthetic imitations. Somewhere, aliens were studying the Federation, using techniques beyond human developments. The trail led back to Cerberus and the Lord who ruled that planet.
The Federation had its own techniques. They took a criminal named Qwin Zhang and stripped her mind of all memory and personality. Then they poured into that empty receptacle the full mind of the Federation's best operative. They exiled her to the prison world of Cerberus. The mission: Find the Lord who ruled, kill him, and take over. Too bad there were things about Cerberus they couldn't know!
