Panic It's the last ever installment of The Hitchhiker's Guide To The Galaxy, with a brand new full-cast dramatization of Mostly Harmless, the final book in Douglas Adams's famous trilogy in five parts. While frequent flyer Arthur Dent searches the universe for his lost love, Ford Prefect discovers a disturbing blast from the past at The Hitchhiker's Guide HQ. Meanwhile, on one of many versions of Earth, a blonder, more American Trillian gets tangled up with a party of lost aliens having an identity crisis. And just when Arthur thinks he has found his true vocation on the backwater planet of Lamuella, the original Trillian turns up with more than a little spanner in the works. A stolen ship, a dramatic stampede, and a new and sinister Guide lead to a race to save the Earth ... again. But this time, will they succeed?
