Bess McNeill is a young and beautiful Scottish woman who carries the burden of a troubled past, involving her struggles with mental health following the tragic death of her brother. Her life takes a significant turn when she decides to marry Jan Nyman, an oil rig worker from Denmark who is not a churchgoer. This relationship creates a rift between Bess and her community, particularly her strict Free Scottish Presbyterian Calvinist church. Despite the disapproval surrounding their union, Bess remains steadfast and maintains an unwavering belief in her love for Jan, which is as childlike as it is pure.
Throughout their relationship, Bess finds solace in her conversations with God during her regular visits to church, convinced that He is responding to her prayers. In moments of longing, she expresses her feelings for Jan through their heartfelt phone calls, filled with declarations of love and their shared desires. However, as time passes and Jan is away on the oil platform, Bess's neediness intensifies, leading her to pray fervently for his safe return. Her prayers are seemingly answered when Jan suffers a severe injury in a tragic industrial accident and is flown back to the mainland. Overwhelmed by guilt, Bess begins to believe that her selfish request to God was the cause of Jan's suffering, interpreting it as divine punishment.
As Jan confronts the reality of his incapacitating injury — leaving him unable to engage in sexual intimacy — he asks Bess to find another lover. This request shatters Bess, sending her into emotional turmoil. Following a failed suicide attempt by Jan, which leaves him unconscious, their relationship takes a desperate turn. Jan insists that her discovering intimacy with another man would lift his spirits, reinforcing Bess’s belief that such acts align with God's wishes and demonstrate her undying love.
Despite the deep-seated revulsion she feels at the thought of being involved with other men, Bess struggles to reconcile her inner conflict as she embarks on a path of sexual debasement. In a moment of desperation, she approaches Jan's doctor, hoping to fulfill Jan's request, but when he turns her down, she starts picking up men from the streets, confusing pain and passion in increasingly brutal encounters. The village is scandalized by her actions, leading to her excommunication from the church. In a moment of defiance, she asserts, > "You cannot love words. You cannot be in love with a word. You can only love a human being. That's perfection," reflecting her profound understanding of love in its most raw form.
Faced with potential danger and being deemed a threat to her own well-being, Dodo, her sister-in-law, alongside Jan's doctor, decide that the only course of action is to have Bess committed, removing her from Jan's life, whom they believe is nearing death. In a desperate bid to prove her love, Bess makes what she perceives as the ultimate sacrifice: she returns to an abandoned ship, where sailors violently assault her. In a tragic reunion, Dodo and Mrs. McNeill find Bess gravely injured in the hospital, where forgiveness is extended for her choices.
Ultimately, Bess's church condemns her as lost and destined for hell. However, unbeknownst to the church elders, Jan and his friends have taken steps to insulate Bess's identity from the church's judgment by swapping her body with bags of sand in her sealed coffin. Dodo stands up against the church's authority, passionately stating that no one has the right to damn Bess. As the narrative draws to a close, we witness Jan, against all odds and after intense struggle, recovering enough to bury Bess in the ocean, grief-stricken. The story culminates with an element of magical realism: Bess's body fails to register on sonar, and the church bells resonate high above, leaving a lingering sense of wonder and unfinished business in the ethereal embrace of the sky.
