Jazzi, Ansel, and Jerod are helping a friend convert a barn into a house when Jerod's dad asks Jazzi to help find who murdered one of the mechanics who worked at his car repair shop. Vince was one of the first mechanics he'd hired, and Eli's shocked when he finds that recently, Vince was caught cheating clients into repairs they didn't need. It's out of character, but soon, they discover Vince was frantically trying to cover a gambling debt of his brother's. He was so desperate, he even sold the motorcycle that he'd worked on and loved for years without telling his wife. Between searching for answers and converting the barn, Jazzi's good news still doesn't go unnoticed. She and Ansel are going to have their first baby, and her husband and cousin are determined she won't do anything unsafe on the job. They'd wrap her in bubble wrap if they could, but she won't have any of it. She has to work just as hard to make them quit pestering her as she does to help Gaff solve the case.
