A year has passed for the community of survivors. Ian and his team are still making dangerous forays to the ravaged surface in search of food and medicine, forced to go ever further each time. But one day, just as they're about to be killed by one of the exterminator robots that constantly patrol the city, they're saved by an old acquaintance not even Ian still hoped to see again: SAM, the strange robot that seems to want to protect the boy -

Winter blankets the wreckage of the world. In the snow-covered ruins, four children scavenge for supplies to feed their dwindling group of survivors.

And without Ian, without his optimism, the survivors are losing hope. Until, one day, they recover the electronic device that their friend had built to communicate with SAM...

Convinced that they are the last survivors of the human race, Ian and his friends have decided to go in search of the command centre controlling the machines that hunt them so mercilessly.
