It looks like young Keith Gridley will have a lonely summer, until he meets a talking mouse named Ralph. Ralph takes an immediate liking to Keith's toy motorcycle and can ride it just by making a motor noise. Ralph even acts heroically when Keith comes down with a nasty fever, while dodging cats, owls and a guest's noisy dog.
