Charming and kind, Elwood P. Dowd has only one character flaw: an unwavering friendship with a six-foot-tall, invisible rabbit named Harvey. In order to save the family’s reputation, Elwood’s sister, Veta, takes him to the local sanitarium. But when Dr. William Chumley mistakenly commits anxiety-ridden Veta instead of her brother, it sets off a hilarious whirlwind of confusion and chaos as everyone tries to catch a man and his invisible rabbit.
