A meteor shower blinds most people in the world and at the same time spreads triffid plant spores which quickly become animated. Bill Masen, a merchant navy officer who has been lying in hospital overnight with his eyes bandaged, is unaffected and leaves the next day. While at a railway station, he comes across an orphaned schoolgirl named Susan who, having spent the night in the luggage van, is unaffected too. He helps her escape the groping crowds and they commandeer an abandoned car in order to reach his ship. On their way the car gets stuck in mud and while they look for stones to gain traction a mobile triffid ambushes them and they barely escape.
