Three individuals, Adam, Mike, and Neil, attend a 12-step support group for sex addiction in New York City. Adam, who has been sober for five years, starts dating Phoebe, a cancer survivor who is unaware of his addiction and presents a challenge for maintaining his boundaries. Mike, a seasoned group leader, has his own struggles at home with his wife, who turns to alcohol for comfort, and his troubled son Danny, who suddenly resurfaces in his life after years of estrangement. Neil is a young emergency room doctor who compulsively engages in inappropriate behavior, eventually facing professional consequences and beginning his journey toward recovery with the help of Dede, a quirky and free-spirited woman he meets in the group.

As their lives intersect, each character grapples with the complexities of addiction and relationships. Adam is torn between his developing feelings for Phoebe and his commitment to sobriety. Mike’s rigid control over his family begins to unravel as he confronts his son's return and his wife’s dependency issues. Neil learns to open up about his problems and starts to form meaningful connections, despite his resistance. Through mutual support, setbacks, and triumphs, they navigate the challenges of staying sober while seeking connection and redemption in their personal lives.
