The Universe is home to powerful sources of energy. Black Holes, Supernovas, double strength coffees… the Doctor has intimate knowledge of them all. The one that fascinates him the most however, is the human spirit. On the way to a tomato festival in Buñol, Spain to witness the largest food fight in the universe, the Doctor and Rose make a quick stop for proper attire on Mallonious Prime, largest shopping mall in the galaxy.

The Doctor and Rose arrive to find the Grand Mall seemingly empty. They discover news reports of horrible accidents, all involving the overhead Grand Motorways. Just their sort of thing, the Doctor decides to investigate, but not before being taken hostage by the masterminds of the motorway accidents. Rose, afraid and alone, sets off to find the Doctor. Only together can they solve The Mystery of the Motorway.

Featuring the Doctor as played by David Tennant and Billie Piper as Rose Tyler from the hit BBC One Programme
