"The Die Is Cast" is the 67th episode of the television series Star Trek: Deep Space Nine, the 21st episode of the third season. It concludes the story begun in the previous episode, "Improbable Cause".

Garak has to interrogate Odo to prove his loyalty to his former mentor as a Tal Shiar – Obsidian Order attack on the Founders is underway.

Garak and Odo have not been heard from on Deep Space Nine in several days, following their departure in a runabout to investigate an attempt on Garak's life. Bashir fears for his friend Garak; O'Brien reminds him that no debris from their runabout has been located, making it unlikely that it has been destroyed.

In Ops, the crew is alarmed when a large Cardassian-Romulan fleet decloaks. The fleet ignores the station's hails and proceed through the Wormhole to the Gamma Quadrant.

On the lead ship of the Cardassian-Romulan fleet, Enabran Tain and Garak reflect upon their past times together in the Obsidian Order, the Cardassian secret police. Garak says that he intends to use his newly regained power to exact revenge on several old adversaries, including Gul Dukat, which Tain assures him he will be in a position to do when their mission is complete. Romulan Colonel Lovok, who is immediately suspicious of Garak, informs Tain that the fleet has recloaked and has set course to the Founders' homeworld at Warp 6, as traveling any faster risks detection, even through their cloaking device, by the Jem'Hadar. Tain instructs Garak to question Odo, but Odo does not offer any additional information.
