Last week on "The Young and the Restless," Billy decided to invest with Kevin and Mariah in software that was guaranteed to prevent internet hackings. In an impulsive move he placed a bet on a horse in hopes of doubling his money as he needed $2 million to invest. However, his bookie told him that his horse lost, and Phyllis got mad at him for betting money that he didn't have.

Everybody got ready for Stitch and Abby's wedding at the Top of the Tower, and Ashley asked Neville to be her date to her daughter's nuptials. Adam asked Abby to put Luca and Marisa on the guest list, and as the women of the Newman family protested, Adam said that it was a gesture in good faith, and Nikki and Abby finally agreed to do so.

Jack arrived for the wedding and Billy asked him for a $2.2 million loan. Jack realized that Billy lost a bet and he told him that he can't unfreeze accounts or loan him the money. Later, at the garage, Billy's bookie showed up and demanded for him to pay up. Billy told him that he can pay after the wedding, but the bookie refused to let him go. Another man appeared and the two beat up Billy and left him unconscious behind a car.

Upstairs, the wedding began and Victor walked with Abby down the aisle. As the ceremony was about to begin, Ashley collapsed and fell off her chair. She regained consciousness after a few minutes and Ashley insisted that she's fine and that she's staying for the wedding. The ceremony resumed and Abby and Stitch exchanged vows and the two were finally married.

After the celebration, Noah entered the garage, got into his car and accidentally put his car on reverse. He drove off, not hearing Marisa calling his name. She saw Billy and called for an ambulance.

Will Billy survive? This week, the Abbotts gather after Billy is rushed to the hospital as Noah, who thinks that he was the one who caused Billy's accident, tries to cover his tracks. Meanwhile, Dr. Neville gives Ashley advice as he insists that there is a cure for her condition.
