In Beverly Hills, Los Angeles, Sebastian, a top A-list movie star of erratic temperament, has fired countless assistants.
Leon, desperate and burdened with his mother’s terminal liver cancer, applies for the position of personal assistant for the high salary. He is hired on the spot with just one line—“I need the money”—and signs a harsh contract requiring 24/7 on-call availability and restricted personal freedom.
After being hired, Leon is thoughtful and attentive, learning Sebastian’s daily routines perfectly. He stays overnight at the mansion for late-night standby duties and takes meticulous care of Sebastian on set, gradually breaking through his walls.
Plagued by a lonely, loveless childhood, Sebastian is deeply moved by Leon’s gentle steadiness and develops an overwhelming possessiveness. He secretly pays for his mother’s massive medical bills and resolves all of Leon’s troubles behind the scenes, yet begins to control every aspect of Leon’s social life and daily routine.
Jackson, a fellow actor coveting Sebastian’s resources, deliberately gets close to Leon. He pretends to help find a renowned doctor, while sowing discord in secret and filming intimate moments between the two, planning to blackmail Sebastian later.
For PR reasons, Sebastian’s agent arranges a female date for him on the red carpet. His cold public demeanor contrasts sharply with his private affection, wounding Leon deeply.
Sebastian’s paranoia grows worse. He bans Leon from seeing Jackson, interferes in all his social interactions, and binds him tightly using Leon’s gratitude and his mother’s illness as leverage.
While Leon is thankful for Sebastian saving his mother’s life, he is suffocated by his overwhelming controlling nature. He finally realizes this twisted love is nothing but possession and imprisonment, not true respect.
Jackson keeps escalating their conflicts and holds the hidden footage, waiting for the perfect moment to strike. Red carpet scandals, on-set confrontations, and explosive clashes at the mansion follow one after another.
Torn between gratitude, love, and suffocating confinement, Leon makes up his mind to escape this obsessive relationship once and for all.
