Edge of Darkness (1985)
Emma Craven: Millions of years ago when the Earth was cold, it looked like life on the planet would cease to exist. But black flowers began to grow, multiplying across the landscape until the entire surface was covered in blooms. Slowly, the blackness of the flowers sucked in the heat of the sun and life began to evolve again. That is the power of Gaia. The planet will protect itself. If man is the enemy, it will destroy him.
Ronald 'Ron' Craven: They all drowned.
Emma Craven: I know. I was there.
Ronald 'Ron' Craven: Why didn't you tell me?
Emma Craven: Dad... you were on their side
Ronald 'Ron' Craven: No!
