Zack is a young entrepreneur, who is in the process of developing a dating app. He has teamed up with Abby Newman, who is investing in his project, and knows Tessa Porter and her sister, Crystal, from Chicago.
Shortly after he and Abby started dating, Zack was revealed to be heading up a small sex trafficking ring with international connections. Zack's only other employee, aside from bodyguards, appears to be Alice Johnson. Despite this, nothing shady showed up when Victor Newman did a background check on Zack.
Tessa's sister Crystal was apart of the sex ring, but Zack had Alice send her away. Zack learned from his henchman, Leo, that Alice had betrayed him. Zack gave Alice a call, and she said she needed some time away. Zack said he understood, and gifted with some money that Alice soon learned was fake. That is when Leo got into the car, and tried to attack Alice. Alice got away, and was struck by a car. She was found and hospitalized, but disappeared and it was strongly implied that Zack had something to do with her disappearance.
During a conversation with Scott, Zack realized Scott was onto him, and drugged his drink when Scott chased after Natalia, who had just walked into the bar. Afterwards, Zack helped Scott out of the club, and Scott woke up in bed next to a dead Natalia. Zack planned to leave town, and left Abby a voicemail, breaking up with her. Paul questioned Zack since Scott said he was the last person that he had seen before passing out.
Zack changed his mind, and showed up at Abby's door with balloons to apologize. Abby was furious, but Zack convinced her that he wanted to be with her and they made love. Abby gave Zack a key to the tack house, wanting Zack and her to move in. Scott accused Zack of setting him up, but Zack denied it, and Abby believed him.
Everything came to a head at a party that was supposed to celebrate Design Date, but the party soon became about Victor making his other daughter, Victoria Newman, COO. Abby was devastated and wanted to leave, but Zack convinced her to stay and not let Victoria get to her. Zack was soon confronted by Crystal, Tessa, Scott, and Sharon Newman. They accused him of using Design Date as a front for prostitution. Zack denied it, so Crystal got on the mic and publicly exposed Zack and his connection to Newman Enterprises. Zack grabbed Abby and ran.
Zack drives through the darkness as Abby demands to know who that woman was. Zack says he knew the Porter sisters and they grew up together in Chicago. Zack lies and says he established a legitimate restaurant business and hired the Porter sisters to work for him. They stole from him, and he fired them, so they have been out for revenge ever since. Abby knows he is lying, but Zack says nothing as he continues driving.
Abby asks Zack why he ran if he was innocent. Why didn't he deny everything and accuse the Porter sisters in return. Abby doesn't like Scott, but she knows he is a professional and wouldn't lie about something serious. Zack admits his restaurant wasn't entirely legitimate, and says it doubled as massage parlour. Zack hired the Porter sisters because he wanted them to have a better chance of life. Zack says the business was legitimate, but Abby is disgusted, and can't believe she fell for his lies. Zack says he loves her, and regrets nothing cause it led him to her.
Zack then turns it around on Abby, and says he and her father aren't innocent either. Zack accuses Abby of knowing what Design Dates was really about, and that she didn't care as long as she didn't care as long as it made Newman Enterprises money. So, she and Victor are complicit. Abby demands Zack stop the car and he takes her to his storage unit.
Zack tells Abby he loves her and begs her to run away with him. He knows he feels the same way. Scott shows up, and says that won't happen. Scott tries to convince Zack to let Abby go. He knows Zack has to run, and says Abby will only slow him down. Zack agrees, and tells Abby he loved her before shoving her into Scott's arms, and locking them in the storage unit.
Zack returns to his room where he finds Abby and Scott. He isn't happy to see them at first, but then believes it is fate that he saw Abby again. Abby agrees, and says her family doesn't care about her. She says she'll run away with Zack, and he says he needs tie up a lose end. Zack points his gun at Scott, but Abby says if he wants her to run away with him, Scott must live
Abby says Scott is no threat to Zack, who wonders if Abby slept with Scott. He tells her not to lie to him since sex is his business, and he knows when people are interest in each other. Abby says they didn't, but Zack gets suspicious by the way she is acting and believes she did. Zack points his gun at both Abby and Scott, and calls them low down cheaters as he goes to pull the trigger. Scott lunges at Zack, and a shot rings out. Zack falls to the ground dead, revealing Crystal standing behind him, holding a gun
