After dropping out of college, Annie packs up and relocates to Los Angeles to live with her older sister Marsha. She soon lands a job as a receptionist at David's clinic, starting to navigate life in the big city. The uneasy father-daughter relationship and the memory of her mother's death linger in the background.

Annie's job at the clinic puts her in close contact with her sister's partner, doctor David Mitchell. What begins as flirtation and playful banter gradually becomes more charged. The dynamic sets the stage for a forbidden attraction.

One night, David fails to save his patient Billy, who commits suicide. Annie witnesses the tragedy, triggering painful memories of her mother's death and sparking emotional vulnerability. The incident deepens the emotional stakes between Annie and David.

Following Billy's death, Annie and David share a kiss, and both attempt to rationalize it as innocent. The moment unsettles Annie as she struggles with guilt and the specter of her mother's death. They retreat into a complicated emotional pull toward each other.

Tom hosts a family party where Annie gives him a self-made painting. The painting's style reminds Tom too much of Annie's mother, sparking a fight that ends with Annie walking out. The rift widens, pushing Annie toward bigger life changes.

The next evening, Annie fills in for Marsha to attend a play with David and they end up having sex. Guilt quickly darkens the haze, and their attraction evolves into a full-blown affair. They begin to map out a secret double life.

As the affair continues, David contemplates telling Marsha the truth, but Annie urges him to stay silent to avoid hurting her sister. The emotional stakes rise, with deception binding the trio closer to the brink of exposure.

After attending Marsha's gallery opening, Annie resolves to return to college, choosing a path back to independence and away from the complicated love triangle. The decision signals a shift toward rebuilding her life on her own terms.

David tells Annie he is in love, and they share a kiss in the clinic, sealing a moment of vulnerability. The fragile affair is under threat as their secret stands on the edge of exposure.

A drug-addicted client launches a violent attack on David, leaving him severely injured. Annie rushes him to the hospital, torn between care for him and fear of consequences if the affair becomes public.

When Marsha visits the hospital, the truth about Annie and David's relationship surfaces through a nurse's insinuation about David's 'girlfriend.' Annie admits she is in love with David, and David takes the blame, urging Marsha not to abandon Annie.

In the end, Annie reconciles with both Marsha and her father, who reassures her that she is not responsible for her mother's death. As she prepares to leave Los Angeles, she faces a fragile but hopeful closure and renewed family bonds.
