An Away Team, led by Worf, investigates a barren planet once inhabited by the Koinonians, a race which destroyed themselves in a lengthy war. While exploring an underground tunnel, archeologist Marla Aster is killed by a bomb buried years earlier beneath the surface. Worf rages about the senseless nature of the women's death and plans to offer the Klingon bonding rite to her remaining son, Jeremy. Meanwhile, an energy field is discovered on the planet and Troi senses an alien presence rising upward from it toward the ship. Almost immediately, Jeremy sees his mother who has come, seemingly from the dead, to take him down to the planet.
