Demon and Davi are two eighteen-year-old prostitutes. Introduced to the sex trade by the cruel and cynical Ryu, they live mostly at night in a Paris dominated by perverse clients to please and by luminal, a synthetic drug that shapes their lives. When their friend is brutally murdered and they discover that Ryu is indirectly responsible for her death, the two girls decide to flee to London and try to change their lives before it's too late. Ryu, however, isn't willing to let them go so easily and sets out to avenge the shame she suffered.

A shy and quiet World War II evacuee is housed by a disgruntled old man, and they soon develop a close bond.
