After returning from a year-long Moon mission, Cassie, a NASA botanist, finds herself in a remote cabin in the woods, where her estranged twin sister, Stella, a former NASA architect, has found a new life with climate activist Bryan. Old wounds resurface as the sisters attempt to pick up the pieces of the rivalry that broke them apart.
