Vic's holosuite is under threat from a rival.
A mobster named Frankie Eyes buys Vic Fontaine's holographic hotel and lounge and throws Vic out. Bashir and O'Brien discover that the program can only be fixed by methods that fit its 1960s Las Vegas setting, and resetting it would wipe Vic's memories of the crew. They recruit their friends to rob the casino safe, so that Frankie's boss, Carl Zeemo, will blame him for the missing money. Sisko initially refuses to take part, objecting to the racism of the real Las Vegas of that era, until Kasidy persuades him.
With Kira and Odo working Frankie, Sisko playing a high roller, Ezri drugging the accountant and Nog cracking the safe, the heist survives a surprise lock and Zeemo's early arrival. Frankie is taken away and Vic's lounge restored, and Sisko sings a duet with Vic. The seventh-season episode is a lighthearted break from the war and a celebration of the crew as friends.
