There was a knock on the door… A scientist wakes to find himself alone in a cell. The previous night Alien invaders had collected 217 animal species, including him, for study. They then destroyed all other animal life on the planet. He convinces them that Earth is a dangerous place to live. After they have gone, he hears the second knock on the door. Themes include exploration, genocide, deceit, solitude, “duty”.
