NEW YORK, Aug. 29 (UPI) -- Oscar-winning actress Jennifer Connelly says a snap decision by her character Daniela drives the Season 2 action of her sci-fi series, Dark Matter.

Based on the novel by Blake Crouch, the show is about what happens when parallel lives -- created by the choices people make -- collide.

At the top of Season 2, Daniela, her husband Jason (Joel Edgerton) and their teen son Charlie (Oakes Fegley) are trying to settle in a new dimension after dozens of Jasons from other lives placed them in mortal danger in their natural timeline.

Spoilers ahead.
