Uniformed aliens arrive through the wormhole, beam onto DS9, and start a phaser battle with a team led by Commander Benjamin Sisko (Avery Brooks). The aliens fight their way into the brig where Tosk is being held. Sisko, O'Brien and Odo enter the room as one of the aliens (Gerrit Graham) expresses his disappointment at finding Tosk captured alive; Tosk, it transpires, is the alien Hunters' quarry. The Hunter commands Sisko to lower the forcefield and release Tosk, but Sisko refuses. They discuss the issue and the Hunter agrees to place the wormhole out of bounds for future hunts. As much as he detests this practice, Sisko believes that under the Prime Directive, the law forbidding interfering with alien cultures, he must release Tosk to the aliens.
