The U.S.S. Cygnus is perched precariously at the edge of a black hole... the vast, empty nothingness where space and time end.

Anything that crosses its border enters a universe of the complete unknown. And so begins a story that only Disney's film magicians could tells. A story of robots and humanoids. Of human genius and madness. Of Anthony Perkins and Ernest Borgnine.

And a spectacular descent into the ultimate mystery of the cosmos - The Black Hole.
