Introduction
The Enterprise encounters a strange effect while exploring an abandoned planet - space seems to "wink out" for a moment. They are shocked to learn that this effect is not localized, it seems to have occurred everywhere. Will the mysterious stranger they encounter on the surface help them solve the puzzle, or will he endanger everything, everywhere, for all time?
Lazarus' goatee threatens the fabric of spacetime...
