《宠物》讲述的是：Naive, but brash and sultry teenage runaway Bonnie finds herself lost and adrift in America. The lovely young lass runs afoul of a colorful array of evil oddballs who all treat her like an object: violent criminal Pat makes Bonnie help her kidnap the middle-aged Dan Daubrey; domineering lesbian painter Geraldine Mills wants Bonnie to be her kept girl and uses her as a model; and wicked misogynistic rich sicko Vincent Stackman desires poor Bonnie as the ultimate prized possession in his menagerie of caged female animals he keeps locked up in the basement of his swanky remote mansion.
