In Purgatory's Shadow part one

Worf and Garak respond to a distress call in the Gamma Quadrant, and become captives of the Dominion.

Garak's father is a captive there. He dies while talking with Garak.

Sisko, fearing a Dominion invasion, tries to close down the wormhole, but it does not work..and a Dominion invasion fleet comes through it.

This is an excellent episode!

Can't wait for part two tomorrow.
