When one of Rose Hill's most popular socialites is found dead under mysterious circumstances, nosy amateur detectives and cousins Maggie, Hannah, and Claire are determined to find the killer and prove her son's innocence. In a twist of fate, Police Chief Scott Gordon finds himself in the unique position of assisting the cousins in an investigation that county sheriff's detective Sarah Albright has little interest in. Meanwhile the cousins find that shining a light on the fundraising shenanigans of a local hospital and ripping the lid off a notorious love triangle may prove just as dangerous as cornering a clever sociopath. It's August in Rose Hill and as the old-timers say, "it's the dog days of summer and the snakes will strike at anything." Indeed, several nasty snakes are feeling the heat, and if the cousins aren't careful, someone may be bitten.
