Lonely traveling salesman O'Brien is married to the luscious Fontaine, whom he lives with in a great San Francisco apartment with a balcony you can hold a poker game on, but she can't have kids and is overcompensating by becoming an ace at running his appliance sales business. So, when he meets waitress Lupino on a sightseeing bus on one of his frequent trips to Los Angeles, he is looking for a little innocent companionship that turns into--well, the title says it all. Gwenn is the adoption agency man investigating O'Brian and Fontaine for an adoption. There isn't a great deal of suspense here, nor are there plot twists to amaze and amuse you. Instead, it is presented as a straightforward story of man who, perhaps, loves a bit too much. Lupino's direction is flawless, the acting, right down to the smallest part, is excellent, and the San Francisco and Los Angeles locations are great as well, although there is one clear mix-up when a San Francisco scene is presented instead of a Los Angeles one. The interiors of the apartment and other sets are very well done as well. There is also a tour of Beverly Hills that, in a nice joke, includes Gwenn's house. Well worth watching. ( )
