'Christmas is a time for festivities, family and fun. It's also a time for action, adventures... and aliens. Spend Christmas with the Doctor as he joins the celebrations around the globe, from the pagan past to the distant future, taking in the frozen waters of the Arctic, the rainforests of Papua New Guinea and even a trip to the planet Gloricious. Christmas is an interesting time of year when the Doctor's about. In fact, it's out of this world.'

'Sari Martinez is making a solo trek across Antarctica, sometimes pulling her sled of provisions, sometimes riding on it behind her power kite. It is the Christmas of 2008. Somehow she manages to crash into the only object in the snow: the TARDIS. She recovers enough to make camp and then carries on her journey the next day. She is puzzled not to be able to use her cell phone or GPS but blames solar activity. Later she thinks she sees an aerial dogfight between two aeroplanes and later comes across a vivid pink pile of wreckage that resembles a plane with limbs. Worse happens when night falls suddenly, even though she can still see the sun, but then daylight returns.
Sari tries to radio Snowcap base to tell them that she is less than a day away but finds herself talking to the Doctor. He tells her an unbelievable story about an alien invasion attempt. He says that Snowcap base was evacuated when the Gelidons attacked but he has destroyed their devices for removing the ozone layer in the southern hemisphere. He explains that the dogfight she saw was Steven in a stolen Gelidon craft causing a distraction. Sari struggles to come to terms with this but the description of the Gelidon as giant lobster-like aliens fits what she saw in the snow. When the Doctor says he is in a snowcat that has run out of fuel and is a sitting target for the vengeful aliens Sari asks for his position and tries to find him.
She finds herself racing two Gelidon to reach the Doctor and arrives at the Snowcat just before them. Throwing up her power kite as the Doctor climbs onto her sled they escape with seconds to spare. They return to the TARDIS where the Doctor calls for help (the TARDIS has been damaged while thwarting the invasion). Sari is left looking at the interior of the TARDIS marveling at the Doctor and his amazing ship.'
[The Doctor is the First Doctor. His companion is Steven Taylor.]
