When the police dismiss her story, she sets out with her dog, Pretzel, to find the killer while also managing her colorful dating life and the job she hates at Breaking Blind — the guide-dog school owned by her overprotective parents.

A runaway orphan, young Sonora, persists in a menial job mucking stables in Doc Carver’s travelling stunt show. Her great wish is to become a death-defying “diving girl,” but Doc refuses her pleas. Undaunted, Sonora’s gutsy resolve finally convinces him to give her a break. On the brink of stardom, however, a cruel twist of fate threatens to destroy her dream.
