Fraught with insecurities, Marshall Grissom has spent his whole life trying not to call attention to himself, so he can't imagine he would be remotely suited for the role of time travel pioneer. He's even less enthusiastic about this corporate time-travel adventure when he learns that nudity is a job requirement. The task would better match the talents of candidates like the smart and beautiful Sheila Schuler, or the bristle-tough and rattlesnake-mean Marta Hamilton.

As the project evolves into a clash between science and corporate greed, conflicts escalate. Those contributing the funding are mostly interested in manipulating time travel for profit, and will stop at nothing, including murder, to achieve their goals.
