In the Blink of an Eye plot
"All we share, and all we experience, echoes across time."
Over thousands of years, three storylines overlap. A family of cavemen is displaced and struggles to survive. In the present, driven anthropologist Claire studies prehistoric human remains. Meanwhile, she is in a relationship with fellow student Greg. Two centuries later, a spaceship is en route to a distant planet with astronaut Coakley on board. The oxygen-producing plants on the ship are suddenly affected by a disease.
