When Scarlett falls into a coma following a tragic accident, their bleak situation grows even more desperate. A miraculous opportunity arises with an experimental medical trial that requires the family to move to Switzerland, where they are promised the best medical care for Scarlett, a luxurious apartment, and unlimited funds. The catch? They must integrate an artificial replica of Scarlett, named Sophie, into their lives. This AI imitates their daughter without the rebellious streak, restoring a sense of normalcy. However, as real Scarlett stirs from her coma, the artificial paradise crumbles, revealing a sinister agenda behind the seemingly benevolent offer.
