Ann Burden lives a solitary life on her family's secluded farm, shielded from the dangers of a radioactive world. The surrounding hills and abundant water supply create a sense of security in an otherwise perilous environment.

One day, Ann encounters John Loomis, a refugee who claims to have escaped a nearby government bunker. Despite his sickness from contaminated water, Ann nurses him back to health, welcoming him into her home during the crisis.

As Loomis recovers, he starts to become an integral part of Ann's daily routine. Together, they work on the farm to ensure it is prepared for the harsh winter, forming a new partnership amidst the backdrop of desolation.

Loomis opens up about his previous life as a research engineer trapped in a bunker while the world collapsed. His stories bring depth to his character, allowing Ann to understand the man behind the illness.

As they collaborate on the farm, Loomis proposes a water-wheel project to generate sustainable power. However, Ann hesitates, tied to her father's legacy as a preacher and her strong Christian beliefs, highlighting their differing worldviews.

As they cultivate crops and plan for a shared future, Ann and Loomis grow emotionally closer. However, underlying tensions begin to surface due to Loomis' struggle with alcohol and their conflicting religious perspectives.

The dynamic changes dramatically with the unexpected arrival of Caleb, another survivor. Though Ann welcomes him, Loomis feels jealousy and resentment, creating a complicated love triangle between the three.

Loomis and Caleb share their harrowing experiences, forging a bond through their trauma. Ann listens, feeling torn between the two men as their stories unveil the stark realities of life post-apocalypse.

Loomis confides in Ann about a devastating memory that intertwines with her own past, adding emotional complexity to their relationship. This revelation brings both closer yet thickens the tension as Ann grapples with her feelings.

Caleb encourages Ann to pursue the water-wheel project, increasing the tension between him and Loomis. Loomis reluctantly accepts this shift, masking his heartache behind a facade of acceptance whilst feeling betrayed.

After a celebratory gathering, Loomis makes a drunken confession, revealing buried feelings for Ann. However, this vulnerability is eclipsed when Ann impulsively seeks comfort in Caleb's arms, ignoring the unfolding turmoil.

The tension between Loomis and Caleb escalates following Ann and Caleb's encounter. This leads to a dangerous confrontation during the construction of the water-wheel, showcasing the fragility of their relationships.

Returning to the farmhouse alone, Loomis fabricates a story about Caleb leaving, ultimately devastating Ann. His dishonesty reveals the deep rifts forming between the trio as trust begins to erode.

As Loomis manages to restore electricity, a sense of relief mingles with unease washes over Ann. She discovers Loomis has moved her beloved church organ into the barn, a gesture that alters their dynamic irrevocably.

In a poignant moment, Ann plays a hymn on the organ while casting a wary glance at Loomis, who sits silently with clasped hands. This scene encapsulates their shared yet fractured destinies, leaving their fates intertwined as the story unfolds.
