A detective named Jackson is parked outside a house, making a call to inform his client that he's ready to start observing and collecting proof. He then moves closer to the house, observing a woman named Jennifer doing exercises in tight workout clothes. Over time, Jackson continues to watch Jennifer, taking photos of her without her knowledge.
However, his surveillance starts to feel less like work and more like. obsession. One day, Jackson knocks on Jennifer's door. She answers, curious about his identity.
Jackson calmly explains that he's a detective hired by her husband to investigate her fidelity. He asks to come in, and Jennifer, surprised, allows him entry. Inside, Jackson reveals that her husband suspected her of infidelity, but Jackson assures her that she has done nothing wrong.
He praises Jennifer's beauty and offers his loyalty to help her live freely. Jackson suggests that he can serve as a cover for any affairs she desires, whether with him or others. He doesn't mind who she chooses to be with; he just wants to give her the freedom her husband fails to provide.
