Fast-paced, thoroughly enjoyable. Better than Pastwatch. The ending with Daniger was a little wanting. Sure, he deserved whatever he got, but how it was delivered wasn't quite right.
A group of historians goes back in time to find "the Professor", who is lost back there, using technology of an evil, greedy, corporate scientist, who uses the past to shape the future. The past also supplies detailed floor plans for excavation work in France. Twists and turns galore wrapped up in 32 hours. It would be a shame to make a movie out of it. A mini-series (a real one: 6 or 8 hours) would be better.
Of course, a movie was made from the book. I haven't seen it as of this writing, so I don't know how well it translates. Then again, at this point, I might not remember enough to notice how different the adaptation was.
