. In orbit, the Enterprise crew find the Arcos suffered a warp-core breach and was destroyed, but an escape pod appears to have been launched and start searching the planet for it. They learn that the planet's colonists turned against each other, destroying their surface dwellings and forcing the survivors underground. A warning from the Potemkin from six years earlier warns that the remaining colonists execute any trespassers on the planet.

The crew makes contact with one of two warring factions, the Coalition. Their leader Hayne reveals that the other faction, the Alliance, hold the Arcos survivors hostage, and offers the Enterprise their support in exchange for Federation weapons, which Captain Picard

Intrigued, Picard accepts Ishara aboard.

Through this, Ishara is readily accepted as part of the crew, and Data

and Data remove a proximity sensor that Ishara, like all members of the Coalition, was implanted with that would activate if she had approached the Alliance security sensors; Ishara gives Data the sensor as a memento. The away team transports to the planet and executes their plan, safely rescuing the hostages back to the Enterprise, but Ishara is lost in the confusion. Data searches for her and finds her attempting to disable the Alliance security grid; Ishara reveals that once the grid is down, a large force of Coalition members are ready to attack the Alliance. Ishara's entrusting of the Enterprise crew was all a ploy by Hayne to allow her free access within the Alliance territory. After Ishara attempts to fire on him, Data is able to stun her and revert her modifications on the Alliance systems.

Back aboard the Enterprise, Picard informs Hayne that as Ishara fired upon a Starfleet officer, they could hold her as a prisoner, but instead returns her to the planet. As Data escorts her to the transporter room, Ishara lets him know he was the closest thing to a friend that she had. Data considers his past relationships with both Ishara and Tasha as the Enterprise leaves orbit.
