Once upon a Trailer Park begins with a murder on the streets of the beautiful bird RV Park in Palm Hill, Florida. As residents learn bits and pieces about the crime (some true, some less so), they form and reform theories of the killer’s identity. It’s the park weirdo. It’s the ex-wife. It’s the victim’s employer. For a few couples in the park, it's important to find out the truth - some due to friendship, some from fear, some to protect themselves.

Lorilee Riley has eight cats, a Florida home, and a large lot to maintain. That ought to be enough to keep a senior citizen busy, but when she finds a corpse in her flowerbed, Lorilee wants to know who put it there. Later, the question becomes why the police don't seem to be a hundred percent dedicated to finding out who killed Regina Dean.

Private Investigator Max Dunham is planning a vacation in sunny Mexico when two kids enter his office and ask for help hiring a hit man. They insist their lives are in danger and that murder is the only way they can protect themselves. Max's disbelief is tempered by sympathy. The precocious girl and her taciturn brother are strangers to American society, having grown up in the Amazon jungle. They find much of life in the US incomprehensible, even silly.
