Houston, 1961.

Texas’ slickest politician loses his presidential bid to a good-looking naval hero from Massachusetts. President Kennedy wants to put a man on the moon, and the Freedom Riders are raising morale for local civil rights activists.

Sleepy backwater Houston finds itself short on air conditioning just when things are heating up.

In a seedy downtown office, a well-dressed out-of-towner hires P.I. Harry Lark to tail two D.C. visitors looking to build NASA a space center. The more Harry finds, the more he suspects he’s working for the wrong side, and vows to wash his hands of the case. Meanwhile, Harry’s twelve-year-old daughter Dizzy is puzzling over a mystery of her own—she’s running a lost-and-found out of a suburban garage and is unexpectedly hired to find a missing dad who’s supposed to be dead and buried.

When Harry’s client turns up dead in his office, and mobsters start hounding him for cash, Harry realizes he needs all the help he can get, even if it comes from his daughter. As Harry and Dizzy’s cases converge, one thing is clear: someone wants Houston to look like a lawless Wild West Cowtown. Together, Harry and Dizzy are going to find out who that is.
