The Grand Tour S2 Here

After the disastrous, lawsuit-ridden end of their first season (which involved a stolen bridge, a misplaced tank, and an accidental incursion into a micro-nation), Jeremy Clarkson, Richard Hammond, and James May are banished from international television. Their only chance at redemption? A clandestine, no-rules, cross-continental race organized by a mysterious, unseen benefactor known only as "The Concierge."

Clarkson's voiceover: "And on that terrible disappointment... we're back."

The trio discovers that their "Amazon" studio tent has been repossessed. In its place is a single, battered Tesla (pre-towed by a diesel generator) containing a VHS tape. The tape shows a shadowy figure (voice acted by the late Sean Connery via archive audio) offering them one last shot: "The Grand Tour: No Audience. No Borders. No Sanctions. Follow my clues. First one to the abandoned Mir space station replica in the Kazakh desert wins... your careers."
