Blue Sky

Hank and Carly relocate from Hawaii to a remote military base in Alabama, bringing their mounting marital strain with them. Hank's demanding nuclear career creates pressure at home, while Carly's fragility and restlessness intensify the domestic tensions.

Hank meets base commander Colonel Vince Johnson, who dismisses the underground testing plan codenamed 'Blue Sky' despite the supporting science. The rejection marks the first public setback and foreshadows the power struggle that will unfold between Hank and Vince.

Vince's wife Vera invites Carly to a social gathering of the base officers' wives. Carly becomes intoxicated at the party and performs an exotic dance, prompting Vera and Vince to decide how to address her behavior.

Alex begins a relationship with Vince's son Glenn. On their first date, they discover what appears to be a dud grenade; when it detonates, their relationship is exposed, giving Vince motive to remove Hank from the picture.

Carly is invited to participate in a base officers' wives dance recital and commits to rehearsals. The activity provides her with purpose and a path to draw attention away from the home front tensions.

Hank travels to the Nevada Test Site to supervise the first underground detonation under Lt. Col. Robert Jennings. He believes the test is necessary, but the assignment will pull him away from domestic conflicts and set up the later fallout.

During the test, Hank spots two cowboys in the testing area and asks Robert Jennings to abort for their safety. Robert refuses, ignoring the cowboys' presence and sending Hank back to Alabama, escalating the feud between Hank and the project leadership.

While Hank is away, Alex and Glenn uncover that Vince orchestrated Hank's removal so he could pursue an affair with Carly. The revelation compounds Carly's concern that the power structure at the base is manipulating personal lives for personal gains.

During the dance recital, Hank learns of the affair and reacts violently. His actions cause Carly to be pushed out of a window and hospitalized, and Hank is subsequently arrested.

Hank is arrested after the incident. Vince offers Carly a choice: have Hank court-martialed or commit him to a psychiatric facility. Hank wishes for a court-martial to publicize the cowboys' report, but realizes he has been set up, and military police transport him to a hospital for heavy sedation.

Suspecting foul play, Carly digs into Hank's documents and uncovers the report on the cowboys. She drives cross-country with her daughters to find the cowboys and pressure them to share their side of the story.

When the cowboys refuse to come forward, Carly steals a horse and goes into the test site to reenact their experience, drawing media attention. Robert Jennings is forced to release both Carly and Hank as a result.

Carly returns home to find Hank waiting; Hank has resigned his position, and Vince is relieved of his duties. The couple begins to rebuild their life with a new sense of purpose.

Hank announces a private-sector job opportunity in California and the family relocates there to start anew, marking a hopeful new chapter away from the base's turmoil.
