When Sam's former boss wakes up months later demanding to resume his duties, she is tasked with supervising this egotistical expert with a scalpel who never acknowledged her stellar talent. Complicating matters, the caustic and arrogant Griff also happens to be her father. As he defies Sam's authority and challenges her medical expertise, the big question becomes whether this father and daughter will ever be able to mend their own relationship as expertly as they heal the hearts of their patients.

When Dr. Sam Griffith refuses to concede her role as chief, her father Griff orchestrates a costly surprise. Also, Sam's mother, hospital administrator Vivian, turns to her new spouse, therapist Asher Pyne, for help navigating the battle between her daughter and ex-husband.
