Dr. Daniel Westin is a scientist at government think-tank KLAE Corporation until he is rendered invisible by a formula he concocted. Upon discovering that the government intends to use his formula for evil, he destroys the only batch. With no way to become visible again, he dons a realistic face mask and gloves and becomes a crime-fighting agent for KLAE while also working in the lab with his wife, Kate, in an attempt to rediscover his formula.
