David Hyde Pierce, playing an alien (credited as infinity-cubed in the opening credits), narrates a courtship in a late-20th century American city as an extraterrestrial nature documentary. The relationship "footage" is played straight, while the voice-over (with its most often wildly inaccurate theories) and elaborate visual metaphors add comedy.

Ping is a chihuahua rescued from the pound by nearsighted Ethel, who thinks he's a cat. When a pair of bumbling thieves try to break into Ethel's house to steal the money they think she has stashed away, only Ping can foil their plans.
