Still recovering and weak from his recent surgery, Rush insists on working to repair damage and find out more about the ship. As he and the scientific team are working, the ship drops out of FTL - but no stargate is detected nearby. Rush gets reports that a star is visible, but the crew is stumped as to why no Ancient seeding ships marked its presence.
Soon Rush discovers an Earth-like planet in the star's range. The crew is excited, but this is a further puzzle: Given the star's age, the planet should be a molten ball of rock. Officers and scientists make a recon trip to the planet and discover breathable air, drinkable water, plentiful food and no apparent predators. As they conduct a flyover on their way back to Destiny, however, they discover a mysterious, giant obelisk.
Rush deduces that an alien race, far more advanced than even the Ancients, must have created both the star and the planet. Because of the gravitational pull of the star, Destiny is on an elliptical course around the planet, giving the ship two windows during which a shuttle can reach the planet and make it back to Destiny. Rush and Young, attempting to work together after the recent coup, devise a plan to send a shuttle of military and civilian team members to the planet to gather resources during the month in between those two windows, then return to Destiny with water and food. Eli cautions against this plan - the aliens who ostensibly built the planet may be hostile - but Young contends that it's worth the risk.
The mild conditions and natural beauty of the planet - and relief from the drudgery of Destiny - soon creates a feeling of comraderie and joy, and some team members, including Dr. Caine, start to think that Destiny may have been guided to this Earth-like planet by a higher power. As TJ and Chloe are researching flora on the planet, Chloe makes the startling discovery: TJ is pregnant. Although TJ wants to keep quiet about it, she begins to think of raising her child on the planet.
Conditions on Destiny continue to be grim: Brody and Dr. Park have had limited success in attempting to repair a shuttle, and other crew members, while exploring new areas of the ship, discover strange devices in one of the bays - but have no time to investigate what they might be used for.
Chloe wonders if Dr. Cane is right about the planet being their true "destiny." Just as she rhapsodizes on the possibility of their being meant to be there, she and Scott notice a blue beam emanating from the obelisk. Destiny is almost back in range, and the planet crew prepare, sadly, to go "home."
Dr. Caine makes the case that the aliens will be benevolent, and maybe even help them get back to Earth, and TJ tells Scott that she's decided to stay. Scott tries to persuade her otherwise, but she reveals her pregnancy to him, and he quickly surmises that Young is the father. With this news, Scott reports to Young that a group, including himself, want to stay on the planet, but Young refuses. He offers to leave one of the shuttles for the defectors, contingent that all military return to the ship. Under these conditions, Scott, TJ and Chloe are compelled to return, but carry their doubts about the planet's meaning back with them.
