An aspiring fashion designer, Eloise, relocates from her rural home to the bustling heart of London, pursuing her dream of studying at the prestigious London College of Fashion. Infatuated with the allure of the 1960s, she is an oddity in the modern world, with a peculiar ability to sense the supernatural. Her new life turns sour as she struggles to fit in with her contemporaries, leading her to move out of her dormitory and rent a room from the elderly Mrs. Collins. Eloise immerses herself in her design work, where she finds solace encapsulated in a bygone era's music and style.

Eloise's talents and ghostly sensitivities intertwine when she sleeps, transport her back in time to the 1960s. There, she inhabits the life of a dazzling young singer, Sandie, living out her dreams vicariously through her experiences in the past, night after night. Mesmerized by the neon glow of Soho and the throbbing pulse of its music scene, Eloise forms a deep connection with Sandie's aspirations and charming manager, Jack. As Eloise's waking and dreaming lives bleed together, the glamorous veneer of the past begins to crack, revealing a darker underbelly. She starts to unravel the disturbing truth behind the glittering façade of the 1960s nightlife, which threatens to grip her reality in terrifying ways.
