chunk: Captain Jean-Luc Picard wakes from a nightmare in which he relived his assimilation by the cybernetic Borg six years earlier (shown in the television episode "The Best of Both Worlds"). Starfleet informs him of a new Borg attack against Earth, but orders the USS Enterprise-E to patrol the Romulan Neutral Zone so as not to introduce an "unstable element" to the fight. Learning that the fleet is losing the battle, the Enterprise crew disobeys orders and heads for Earth, where a single, damaged Borg Cube opposes a group of Starfleet vessels. The Enterprise arrives in time to save the crew of the USS Defiant, which is being commanded by Lieutenant Commander Worf. After Picard hears Borg communications in his mind, he orders the fleet to concentrate its firepower on a seemingly non-vital section of the Borg ship. The Cube is destroyed after launching a smaller sphere ship towards the planet.
