At thirty-five, Alicia leaves New York for San Francisco, where she meets Angie and Lucas, a radiant and charismatic duo who draw her into their orbit. Lucas, a gifted musician, creates enchanting compositions, while Angie, a free spirit, spends her days reading, visiting museums, and riding her motorcycle. Alicia becomes infatuated with their unique and alluring personalities, and her daily life begins to revolve around them. As Alicia becomes more entangled in their lives, they begin to form an exclusive and increasingly volatile threesome rife with sensuality and imbalance. She eventually quits her job and moves in with the couple, taking on the role of caretaker for Angie’s unexpected child. The trio’s relationship mirrors the dramatic crescendo of Led Zeppelin’s classic hit, "Stairway to Heaven," as their lives become intertwined in a complex dance of passion, jealousy, and obsession.
