Traveling from New York to Italia, pretty Mary rushes into moody macho lawyer Tito. The girl immediately falls for the guy with the gruffy manners and in an very impertinent way, she leans on him as she gets in trouble: Not only that she gets tied up in her suite by some Gangsters, but also, her new husband is found dead.
Unfortunately the movie The Grumpy is not yet available on HBO Max.
