Captain Talia Valentine is an ambitious young astronaut, whose return to Earth is interrupted when she crash-lands on a lonely asteroid. Laika is a little stray dog from the streets of Moscow, who has been stranded on that same asteroid for a very long time... Talia is in a one-track mind about finding her way off of this forsaken rock. Laika just seems thrilled to have someone to play with her. But when fixes fail, and unexpected communications bridge the expanse between Talia and the Earth, she realises that Laika may be the key to finding her way home - wherever that ends up being.
