Tripods

In the year 2089, an alien race stalks the land in towering machines known as Tripods. They have taken over the earth and enslaved mankind with a mind-controlling device, ceremoniously implanted at adolescence. Will Parker, desperate to escape this ritual, leaves the village with his cousin, Henry and attempts to link up with the human resistance movement.
