Deep within the Zone, a bleak and devastated forbidden landscape, lies a mysterious room with the power to grant the deepest wishes of those strong enough to make the hazardous journey there. Desperate to reach it, a scientist and a writer approach the Stalker, one of the few able to navigate the Zone's menacing terrain, and begin a dangerous trek into the unknown. Tarkovsky's second foray into science fiction after Solaris is a surreal and disturbing vision of the future. Hauntingly exploring man's dreams and desires, and the consequences of realising them, Stalker, adapted from Arkady & Boris Strugatsky's novel Roadside Picnic, has been described as one of the greatest science fiction films of all time.
