Jack Lemmon stars as the playboy landlord Hogan, a swinging bachelor. Women are mere playthings to him, plus he's a master con man. His bachelor pad is a holy temple of seduction: blood-red walls, African sculptures, a well-stocked cocktail bar, a switch-operated fireplace, and mechanized violins that play romantic music at the touch of a button. He walks around wearing a scarlet cardigan (with matching socks and shirts) and a devilish smirk. As the landlord of a Californian apartment block, he only rents rooms to gorgeous single women at just $75 a month.
