Every Friday night in the idyllic seaside town of Pacific Cove, CA, the Roundup Crew, a group of dog-loving friends, meet at a neighborhood wine bar for Yappy Hour. When Rachel, the owner, mysteriously leaves town and asks her sister, Maggie (who is neither pet friendly nor business savvy), to run the bar in her absence, things get complicated fast. Maggie arrives to open up and finds a body sprawled on the floor, and even worse, an incriminating letter with Rachel's name on it nearby. On impulse, she hides the letter from the hunky detective, Officer Brad Brooks, who's dispatched to the scene. When Rachel is declared the top suspect by the police, Maggie decides to investigate on her own.
