Ray and Rachel make it to Boston together on foot. Boston is covered with the red weeds, some living, some dying. The Martians seem to have been stopped, but no one knows why. They witness a tripod come crashing to the ground after being attacked by a nearby Army detachment and a door opening up to reveal a flood of red liquid followed by a dying Martian. Ray and Rachel make their way to Mary Ann's house where they are reunited with Robbie. In the final scene, the camera pans over the destroyed city, focusing on a tree bud, then a water droplet, and finally the multitude of microscopic organisms living in it. The narrator says in a voiceover: 'From the moment the invaders arrived and breathed our air, ate and drank, they were doomed. They were undone, destroyed, after all man's weapons and devices had failed, by the tiniest creatures that God, in His wisdom, put upon this earth. By the toll of a billion deaths, man had earned his immunity, his right to survive among this planet's infinite organisms, and that right is housed against all challenges...for neither do men live nor die in vain.'
