We get to follow the inner workings of the Psi Corps. Bester gets to take care of two new young recruits, to show them the ropes. Meanwhile a telepath at the training facility, has become unstable - and are killing other telepaths. Bester needs to hunt down his old student, who was at one point very close to him, and the two new recruits are given a scary crash course in the practice of the Psi Corps. The killer, a mindshredder, takes refuge to Babylon 5 - and Bester must yet again go back to his least favourite place in space. It's of importance that nobody finds out about the inner problems within the Corps.
