A LIFE ILLUMINATED follows trailblazing marine biologist Dr. Edie Widder—one of the first women in her field and one of the first humans to explore the ocean’s twilight zone—as she descends 3,300 feet into the ocean’s darkest depths. From capturing the first-ever footage of the elusive giant squid to unveiling the glowing mysteries of deep-sea bioluminescence, Edie embarks on her most daring quest yet: to document a bioluminescent phenomenon that could change how we understand life on Earth.
