Time travel has a funny way of catching up with you, and Dale was discovering this was a very real problem indeed.
With no memory of saving the world, as reality was set right again, Dale wakes up and begins to repeat exactly what led to the problem in the first place.
Except he doesn't; things are different.
And Amanda? Something is slightly 'off' about her, but that's the least of his worries as reality crumbles and they have to fight not only for their own sanity and survival, but save the world (again) and make their way through the confusion of the past, present and distant future.
Spanning timelines and a smattering of exotic (and not so exotic) locations, their confusion and fear pale into insignificance once they discover the real cause of all their problems: The Chamber. It's a reality, just not one you'd ever want to get trapped in.
Time travel really is a confusing business.
