Star Trek: Deep Space Nine – The Complete Season Four is a DVD release containing all of the episodes which were broadcast during the series' fourth season.
From the DVD booklet:
- Welcome to the fourth year of the adventures of Deep Space Nine, remote and abandoned Cardassian outpost stationed on the very edge of the known universe.
- Beset by paranoid Klingon forces led by the ferocious General Martok, Sisko calls for the one man who can deal with the unpredictable ally: Starfleet's first Klingon officer – Lt. Commander Worf.
- While the hunt for Changeling infiltrators continues on Cardassia, Qo'noS and Earth, the crew of Deep Space 9 deal with additional complications. Sisko fights a plot to overthrow the leadership of the United Federation of Planets. Dax faces expulsion from the Trill Homeworld and the enforced death of her symbiont.
- Kira joins forces with the hated Gul Dukat not once, but twice. Odo must accept Kira's relationship with a powerful Bajoran politician. O'Brien lives through 20 years of hard labor in an alien prison.
- After a visit to Roswell, Earth, in 1947, Quark is forced to sell his remains on the Futures Market, despite still being alive. And Julian Bashir lives out his fantasy as a 1960s secret agent.
- While Deep Space 9's officers soldier on, the Klingons, the Cardassians, the Maquis and the Jem'Hadar seem determined to bring the battle to Starfleet.
- Welcome to 2372. It's going to be a long and eventful year...
