Follow the intergalactic adventures of Capt. Jean-Luc Picard and his loyal crew aboard the all-new USS Enterprise NCC-1701D, as they explore new worlds.

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.
