Safari Adventure is a small but popular zoo that entertains visitors from all over Texas—until one morning when most of the animals escape and a body is found on the premises. Game warden John Marlin works closely with the sheriff’s office, at first to capture the animals, and then to solve the mystery of the missing zookeeper. But local good old boys Red O’Brien and Billy Don Craddock just might figure it all out first, after they pick up a hitchhiker with a questionable past and some inside information that makes him a prime suspect.
