Mike and Danny decided to try out Delinda's new idea for the Montecito: singing karaoke. They belted out their rendition of the classic, 'Ebony and Ivory.' Danny was mystified on why all the ladies wanted attention from Mike. Mike bragged that he could have any one of the girls in the casino. Delinda pointed out a beautiful woman and challenged Mike to pick her up. As Mike walked over, Delinda explained to Danny that the woman she pointed out, Ava, was a born-again virgin she had befriended the night before.
Ed called Danny and Mike on to shift early to uncover a blackjack scam that was going on in the Montecito. Danny was sent out on the floor to watch the plan in action. He quickly rounded up the accomplices involved and brought them upstairs to Ed. After he questioned them, Ed suspected there was somebody else pulling the strings' someone they didn't have in custody.
Sam and Mary were under major stress to pull off a multi-million-dollar wedding at the Montecito without a hitch. The groom-to-be, Jarrod, was a well-known customer at the casino and Sam wanted to give him the ultimate wedding.
Sam and Mary freaked out when they heard that the bride Lissie's $100,000 dress had been stolen. They called Mike to investigate. The bride declared that the wedding would be off if she couldn't wear the dress.
Danny found a similar blackjack scam on the floor. He brought the accomplices up to the security room to see Ed. While Ed questioned one of the men, he began to think that they were in recent contact with the accomplices from the other blackjack scam.
Delinda hired a new waitress, Patty, but it was not working out. Patty had a tendency to spill her beverages on customers and to karaoke sing during her shifts at work. Delinda wanted to fire her, but didn't know how. Instead, she took Patty aside and had her observe some the Montecito's best waitresses.
Mike cracked the case of the missing wedding dress. After reviewing surveillance footage, they tracked the dress down to one of the bellhops. Mike was speechless when he saw Lissie pay off the bellhop to take the dress. Sam was just as stunned when Mike broke this news to her. Sam confronted Lissie and found out that she'd stolen her own dress so she could postpone the wedding. Sam sympathized with the bride-to-be. She encouraged Lissie to talk to Jarrod about her fears of getting married.
During a romantic date, Mike discovered that Ava was a born-again virgin. Mike was shocked by the news and split from the date early.
Danny discovered that the people involved in the blackjack scam were also students at the same college. Danny and Ed showed up on the college campus to try to find some of them. Danny found out that the ringleader was a guy they called Bucky. Ed thought that if they found the students and questioned them again, they'd find Bucky.
Delinda made Mike feel shallow when he told her he'd called off his date early with the born-again virgin. Mike felt it was only right to find Ava and explain to her that he would like to go out with her again. He was shocked when he went to Ava's hotel room and found her with a naked man! She told Mike that he'd made her feel so bad on their date; she'd just gone back to her old ways of sleeping around. Mike felt even worse about this.
After Delinda witnessed Patty spill another drink on a customer, she was forced to fire her. Delinda felt she had done everything she could to help Patty at the Montecito, but she had to do what she had to do.
Danny was shocked to learn the identity of the blackjack scam's ringleader. Mr. Buckman was Danny's high school math teacher and now he was teaching college kids how to scam in blackjack. Ed sympathized with 'Bucky's' story of divorce and debt, so he let him slide. But Bucky had to agree to keep his students out of the Montecito for good.
Lissie admitted all her fears to Jarrod and told him how the multi-million-dollar wedding was too overwhelming for her. Jarrod sympathized with his jittery fianc' and called off the affair. They opted to get married in a small chapel by an Elvis impersonator. Sam and Mary played witness to the nuptials.
After Patty was fired, she headed back to the karaoke booth. She had the crowd on their feet with her rendition of 'Respect.' Delinda saw it as an opportunity to make money. She offered to be Patty's manager and to find her a recording deal.
