Picture the following situation. You catch a bus to go home after a hard day’s work, pay the fare and take a seat. Suddenly there are sirens everywhere, a blinding flash of light, and a series of incredible jolts and accelerations. The next thing you know you’re stranded in an area of absolute desolation with death on the horizon.

Now while this is quite normal for American users of public transport, Britain is a green and pleasant land, so it’s a bit of a shock for the Doctor and his fellow passengers.

So what is the Doctor doing on a London double decker bus? It turns out he’s tracking a newly opened wormhole and the bus he was riding just drove through it. So now the Doctor and his fellow passengers are all stuck on the Planet of the Dead in a wrecked bus. Since there aren’t any Americans with public transport experience around, they are left to their own devices.

Luckily, the passengers turn out to be pretty resourceful. The better half of a sweet old couple from Brixton has psychic ability. There are two likely lads who start repairing the bus. And there’s a mysterious and aristocratic lady in a tight leather body suit who used diamond earrings as bus fare. She’s Lady Christina (Michelle Ryan), and has just stolen a very precious artifact from a museum. Half of the police in London were chasing her when she boarded the bus.

The London police may have their faults but they do know what to do when a double decker vanishes into thin air. They call in the normally hapless but always well intentioned folks at UNIT. UNIT is the United Nation alien rapid response team and this time they have a really good mad scientist, Dr. Malcom Taylor (Lee Evans), on staff.

All of this talent is going to be tested to the full as the Doctor has to cope with crashed alien spacecraft, a disgruntled alien crew, a rapidly growing wormhole and metallic, and planet chewing space locusts. Indeed, it’s a great show, which manages to duplicate some of the sense of joyful adventure from the old Tom Baker days. It’s the combination of the fast pace, originality and happy go lucky style that makes Doctor Who: Planet of the Dead one of the best adventures that any of the Doctors has had.
