As a boy, Mick Ambrose fell in love with cars. Now he owns and operates an auto restoration shop specializing in all things American Muscle. When the black 1969 Camaro Z28 he years ago dubbed Onyx pulls into his garage, Mick forgets his first love in favor of her driver, Logan Gregg. Mick's interested and cruises Logan at a speed worthy of the car he drives.
Logan Gregg's plan to avoid entanglements in his life drives away when he stops at American Muscle to ask a few questions about restoring the Z28 he inherited from his uncle. The owner of the shop is smooth as a well-tuned V-8 engine and twice as hot. Logan is quick to shift gears and take a closer look at Mick Ambrose and the road ahead. When Mick wants to get too close, too fast, Logan backs off. His past holds painful memories he can't escape and the tattoos on his arms aren't just for decoration.
Working on the Z28 brings the men closer, but Mick makes a mistake when he confesses his knowledge of the past Logan wants to keep buried. Mick knows a man has to settle his past to step into his future, but Logan's unconvinced. To slay his personal demon, he'll first have to look it in the eye.
