Denise, an ultra-perceptive life coach, sees clients at home. Between her succession of clients and living with Joy, Denise never leaves the apartment. On her doorstep, she meets Oslo, an unlikely seducer with whom she decides to have a little fun. But very quickly the question arises: should she probe the handsome guy's mind at the risk of ruining everything? One night, an unexpected visitor rings the apartment doorbell.

Denise tries to probe the mind of Jacques, her father, who is clearly suffering from dementia. But it's no use, and the father/daughter relationship becomes strained. Joy, who is very angry with Jacques, does everything she can to get him to leave and return to his nursing home. All that remains is to find the money. Denise could easily take care of this task, but she refuses to fall back into her old ways. To pressure her, Joy decides to take in homeless people: Kevin, Nazim, Mikaela... Little by little, the apartment fills up with strangers whose thoughts intrude on her own...

A dive into the past: childhood, the family home, parents. And above all, friendship. At the age of 12, Denise decides to confide the secret of her superpower to her two best friends, Angel and Melanie... Then comes adolescence, a time of parties and excess; Denise enjoys her superpower without any remorse. It was during this period, while filming her first movie, that Melanie became Joy... Years later, when the friendship between the three had faded, Denise returned to her childhood home with Jérém, her great love. The time had come to reveal her secret to him...

Angel refuses to lend Denise money for Jacques' nursing home, but suggests organizing a poker game at Joy's house, just like in the old days. Denise finally agrees and, for one evening, becomes the legend of underground games once again, uncompromising and undefeated. But things get complicated when Jérém bursts into the apartment, throwing a spanner in the works of their carefully laid plans... Denise finds comfort in Sybil, a client who has recently started consulting her and to whom she feels increasingly close. For Sybil has a rare quality: she always says what she thinks, and always thinks what she says...

Sybil—now a close friend—gives Denise an ultimatum: she tells her to meet her outside on the street. The time approaches and Denise becomes increasingly nervous about going out. To encourage her, Joy enlists the help of the apartment community. To convince Denise to take control of her life despite setbacks, scars, and fears, each person reveals a key moment in their life.

Joy decides to sell her wardrobe to put her past as a porn star behind her. Very quickly, a joyful and colorful crowd invades the apartment, much to Denise's dismay. What was supposed to be a simple clothing sale turns into an impromptu party. Joy, Angel, Sybil, Jérém, Jacques, Kevin, Nazim, Mikaela, Joy's friends, strangers passing through—all these voices jostle for space in Denise's head. What if, somewhere in the midst of this chaos, she finally finds the answers she has been searching for?
