| For Martha Jones, a medical student in Central London, an ordinary day turns into a nightmare when her entire hospital is transported to the Moon. There, she has to battle the Judoon and outwit a blood-sucking Plasmavore - but can she trust a mysterious stranger called the Doctor? For Martha's first trip in the Tardis, the Doctor takes her back in time, to Elizabethan England. When they find William Shakespeare (Dean Lennox Kelly) under the control of deadly witch-like creatures, they must battle forces from the dawn of the universe to stop history being changed for ever. The Doctor takes Martha to the planet New Earth, in the far future. But when they find the streets being ruled by the sinister Pharamacists, they must brave the ordeal of the mysterious Motorway in order to discover the terrible secret at the heart of the city. The TARDIS lands in 1930s New York. In the midst of the Depression, people are disappearing off the streets. Savage Pig Men hide in the sewers and, at the very top of the Empire State Building; the Doctor's oldest enemies are at work, preparing their most audacious plan yet. Dalek Sec is reborn in human form and plans to build a Dalek empire in 1930s New York. While Martha fights for her life at the top of the Empire State Building, the Doctor must enter into an unholy alliance in order to change Dalek history forever.
Martha returns home - could this be the end of her travels with the Doctor? When she discovers her family is caught up in the scheming of Professor Lazarus (Mark Gatiss) and his Genetic Manipulation Device, it becomes a fight for survival, as human DNA twists into monstrous form.
In a distant galaxy, a spaceship hurtles out of control towards a boiling sun with the Doctor and Martha trapped on board. They have only 42 minutes to uncover the saboteurs, but, with a mysterious force starting to possess the ship's crew, the Doctor is running out of time. NEXT>> |
