After "Voyager" manages to destroy a Borg probe by beaming a photon torpedo aboard, Seven of Nine finds data nodes filled with tactical information among the debris. With it they locate a heavily damaged sphere nearby, and Captain Janeway decides to plan a "heist" – invade the Borg vessel while its defenses are down and take its transwarp coil, which will shave about 20 years off "Voyager"s journey. The crew will create a diversion, then send an away team in to steal the technology. Hoping to find information that will give them a tactical edge, Janeway assigns Seven to study her parents' field notes that "Voyager" recovered from the "Raven".
