When Japanese chef Meg O'Connor's mother is killed in a car crash, she comes home to Shady Harbor to find the family business, Harbor Diner, in a bind. Her father has been trying to run it by himself while dealing with a medical condition of his own. On Meg's first day back, the man involved in her mother's car accident is brutally murdered.

As Meg and her sisters jump in to keep the diner running, the investigation into the murder continues. To her horror, all of the evidence seems to point to Meg's new beau, Hunter. Something just isn't adding up and Meg finds it tough to believe that the man she may be falling for could be involved.

When the girl who identified Hunter as the murderer turns up dead, Meg starts to question her own judgement and decides to do some digging of her own, which leads to more questions than answers.

Together with her sisters, Meg finally solves the mystery but the revelation is a shock to them all.
