Voyager spots a Cardassian-designed, self-guided missile carrying a warhead capable of significant destructive force. As it travels towards Rakosan, a heavily populated planet, Torres reports that she's partly responsible for its virtually unstoppable status. When she was a Maquis, she intercepted it and changed its program to assault the Cardassians, but it later went astray and now she's the only hope in stopping it. Torres volunteers to transport to the missile's interior and reprogram it again, but before she can detonate the warhead, the onboard computer tries to destroy her first. Meanwhile, Jonas continues to transmit classified information on the mission to Seska, and Tom Paris finds it more and more difficult to fit into Starfleet's protocols.
