When Kristen's husband dies unexpectedly in a tragic accident, she is left alone to raise their two-year-old son, David, under the crushing weight of grief and financial strain. Struggling to keep their lives afloat, Kristen is blindsided by the arrival of Samuel, a former colleague of her husband, who reveals a devastating secret: her husband owed him a staggering one million dollars. The news deepens her despair, piling insurmountable pressure onto her already fragile existence.

Desperate to provide for her son, Kristen faces an unthinkable choice when Samuel offers a dark bargain-to repay the debt with her body. Initially repulsed by the idea, Kristen's dire financial situation and lack of options force her to reconsider. With no other way to secure a future for David, she reluctantly agrees, believing she will only need to endure conventional acts of intimacy to earn the money she needs.

But Kristen's expectations are shattered when she discovers Samuel's true obsession. Far from ordinary, his desires fixate on dominating and exploiting her most private boundaries, particularly her anal passage. What begins as a reluctant transaction spirals into a harrowing journey of submission, as Samuel subjects Kristen to relentless and perverse forms of torment, pushing her body and spirit to their limits.
