A journey into a fascinating parallel universe—the dark world of creatures at night—opening our eyes to the wonders right outside our door.

When the sun has set, things get interesting with wild animals. Where people wait for buses during the day, a family of raccoons rummages through the trash can. Foxes and skunks search for food, fireflies send flashing signals to potential mates, owls and bats fly overhead. Night is not just a time, but a diverse habitat that we still know too little about. Wildlife biologist Sophia Kimmig is on the trail of the secrets of the night. Not only does she introduce its wild inhabitants, but she also shows what it's like to live in this parallel world—how it came to be, what it looks like, feels like, or smells like—in this fascinating journey into the wonders of the night.
