Tad Bardeaux is lost somewhere in space.
Luckily, his escape pod is equipped with near-perpetual life support, although that doesn't necessarily compensate for the lack of engines or propulsion. Then there's the minor design flaw that caused the hull to permanently fuse upon its launch--it can withstand all kinds of space perils at the small cost of sealing passengers inside.
Trapped inside the escape pod, Bardeaux finds himself travelling through vast stretches of space and time--while looking for a way out of a box that is definitely not bigger on the inside.
