There is something special about the night.

For many, just the idea of it conjures thoughts of starlit skies, romance, of being tucked up in bed. For others, the night means fear, vulnerability and sleeplessness. At night things go bump, owls take wing and foxes prowl.

Overnight is a celebration of all things nocturnal, a hymn to nighttime wildlife, travel, dreams and art.

Along the way, Dan Richards meets a fascinating array of people who labour while the rest of us sleep, and brings their work into the light.

From night terrors to the glow of watching the dawn break on the summer solstice, Overnight will change the way you think about the hours after dark.
