In a drunken stupor, Brandon O'Malley has terrorized his brother Aidan's girlfriend, enraging his brother and the rest of his family. Aidan offers Brandon the choice of rehab or jail, and Brandon reluctantly enters treatment.

While in rehab, Brandon confronts the lifetime of secrets and resentments that fueled his spiral into alcoholism, and these revelations have a major effect on his entire family. When he returns home expecting to resume his supervisory role in the family's construction business, Brandon learns his father has retired and put his younger brother in charge. Brandon is unhappy to be given the job of renovating an apartment building where he loses his heart to an adorable five-year-old tenant named "Mike."

After he falls hard for Michaela, Brandon becomes involved with her mother Daphne, who is running from a past that will later test his sobriety and his mettle as a man.
