Everyone is shocked when a member of the crew is found dead from a gunshot wound. While at first glance it appears to be suicide, the gun is nowhere to be found. The crew is confined to quarters while a search is performed and when the gun shows up in Col. Young's quarters, he becomes the number one suspect. Fearing a mob scene, Young agrees to a trial and cedes command to Camile Wray. Dr. Rush convinces Wray to give him control of the science team and carte blanche with the new Ancient interface, previously kept under guard. But before Rush can unlock its secret, or Young's trial can conclude, both are needed to explore a planet hiding a secret that threatens the Destiny and her crew.
