It’s summertime in Holiday Bay, and between the outdoor dining option provided by the new rooftop bar and eatery, and the summer concert series held on the roof every Thursday night, the Bistro is busier than they’ve ever been. Beck has an interesting case involving a woman whose mother disappeared when she was a child, Amy is entered into the annual clam chowder cookoff, Dawson has an important decision to make, Nikki has a new guy in her life, and Kennedy is struggling with empty nest syndrome while Addy is visiting her brother in Boston. In spite of a few challenges along the way, life for the gang at the bistro seems to be nothing but blue sky and smooth sailing, until an unexpected visitor arrives on the scene and puts a wrench in things.
