Returning to New Earth, the tenth Doctor, played by David Tennant, and Martha (Freema Agyeman), find themselves separated on a sprawling futuristic motorway. While trying to catch up with his kidnapped companion, the Doctor begins to unravel the mystery surrounding the never-ending gridlock, with the help of an old friend, the Face of Boe! But criminals and car accidents aren’t the only things standing in the Doctor’s way, as the giant, crab-like monsters known as the Macra are revealed to live beneath the floating traffic jam.
