The Day of the Triffids (2009)

It's an up-to-date setting of the 1951 sci-fi thriller. With the world blinded and the Triffids set loose, it falls upon a band of scattered, sighted survivors to fight this carnivorous plant invasion. With a brave new world of maniacs, warring factions and renegades, the battle on the streets is not only directed at the purple-headed organisms but a battle to survive the sinister street-army headed by megalomaniac Torrence.
