Set in the 24th century, the series follows the adventures on Deep Space Nine, a space station located near a stable wormhole between the Alpha and Gamma quadrants of the Milky Way Galaxy, near the planet Bajor, as the Bajorans recover from a brutal decades-long occupation by the imperialistic Cardassians. In this episode, a creature called Tosk (Scott MacDonald) arrives on the station from the Gamma Quadrant and befriends Chief Miles O'Brien (Colm Meaney), who tries to help him escape the Hunter (Gerrit Graham) who has pursued him through the wormhole.
