After witnessing a flower blossom from an underground, Martian tree, Sara is visited by Caleb, a love who died in an accident three years ago. Only after seeing the flower, Caleb makes sense of his purpose and pleads for Sara to return to Earth. He leads her towards a room before fading into darkness. Sara alone explores the damaged greenhouse and since the accident, sees Caleb’s dead body. Ready to leave, Sara attempts to use the radio but has a change of heart. She returns to the tree and stands before the naked branch, waiting again for a flower and Caleb to return.
