Kelly Lowell - free-lance ride mechanic...can't decide which she enjoys more: fixing roller coasters, or riding them. But there's more to California-born Kelly than a craving for cotton candy. Beneath the jeans and the, "I'd rather be at Disneyland!" T-shirt is a woman who dreams of her own amusement park.

Mark Delgado - Construction CEO...wants to renovate THRILL-O-RAMA, the condemned amusement park he frequented during a poverty-ridden childhood. He'll give mechanical wizard Kelly half-ownership if she pulls off the risky renovation. But things go downhill faster than The Thriller - the park's old roller coaster.

The couple must solve a ghostly mystery in the past if they want to stay alive in the hard-and-fast present. With everything on the line, Kelly prays she survives the ride of her life!
