there now follows a chase through time and space, with the dalek vessel determined to track down and exterminate the doctor and his friends. the daleks are but fifteen minutes behind and the gap is closing. the first stop is the top of the empire state building in new york city in 1966. the doctor then reaches the atlantic ocean and boards the sailing ship "mary celeste". the crew ventures outside and are mistaken for stowaways. they sneak away in the tardis as the crew searches for them. soon the daleks arrive and the frightened crew abandons ship, all jumping overboard. the next point of landing is a mysterious old house where both dracula and frankenstein's monster have come alive. these terrors stalk the building but also attack the incursion squad when they arrive. in the confusion, the doctor, ian and barbara leave vicki behind, never realising they have simply been visiting a futuristic theme attraction called the festival of ghana, in 1996. the daleks are repelled back into their vessel by the monsters (who are in fact robots), and vicki stows away aboard the dalek ship. she travels in it to the jungle world of mechanus, where the tardis has already landed.
