Danny (Josh Duhamel), Piper (guest star Camille Guaty) and Mitch (Mitch Longley), along with the surveillance room are taken hostage when thieves attempt to steal a rare stamp that is up for auction at the Montecito. Delinda (Molly Sims) and Cooper (Tom Selleck) have an unexpected dinner and Delinda takes this opportunity to try to get to know their mysterious owner. Meanwhile, Mike's (James Lesure) mom discovers he has gotten married without her being there and is irate, but thanks to his quick thinking he convinces her that they haven't gotten married yet and that the big day is Saturday. Excited about the nuptials, Danny (Josh Duhamel) and Delinda (Molly Sims) help to plan the bachelor parties, which gets them thinking about their own future together. Former owner Casey Manning's little brother Vic (Charlie Koznick) pays a visit to Vegas and is interested in only two things -- Sam (Vanessa Marcil) and getting the Montecito back. An unexpected tragedy happens to one of the staffers and stuns everyone.
