Finch, a Sci-fi drama starring Tom Hanks is set in a post-apocalyptic world. It has an interesting plot: A dying man creates a robot to care for his dog. Sounds like a hero, right?
The story breathes through the triad ― Finch (Tom Hanks), Jeff (the Robot) and the dog. Tom Hanks is the solitary human in the Cast Away setting albeit he has Goodyear, the dog for company.

An environmental catastrophe has ravaged the Earth and Finch is perhaps the only human left. Reclusive and rough around the edges, Finch scavenges derelict malls by the day and spends his evenings building a robot. The purpose of the robot – to be a backup guardian for the dog after he’s gone.
