"Good Witch" will take viewers on a new magical journey with Cassie Nightingale (Bell) and her bright, young-teenage daughter Grace (Madison), who shares her mom's special intuitive charm. When Sam, a doctor (Denton), and his teenage son move in next door to Grey House, they are immediately charmed by the 'magical' mother-daughter duo and wonder is it really magic, a lucky coincidence or just a special intuitive insight only this family possesses? Based on the network's most successful Original Movie franchise of all time, "Good Witch" will inspire with each intriguing episode and will have viewers immediately charmed by the quaint town of Middleton - which is in store for new changes, big surprises, and, of course, a little bit of magic!

In the "Good Witch" season three, Cassie Nightingale (Bell), along with the residents of Middleton, wait with anticipation as the rare plant, the Middleton Merriwick, readies to bloom again for the first time in decades, promising the most magical year of all. Martha (Catherine Disher), devises a strategy to let the world know Middleton houses the one-of-a-kind Merriwick, escorting a curious botanist from the University to the botanical gardens to study its wonder. When Grace (Madison) learns secondhand that Sam (Denton) and Cassie are officially together, causing Grace (Bailee Madison) to feel hurt that her mother didn't tell her first. A cryptic text from Nick (Rhys Matthew Bond) leads Grace to think he plans to ask her out, but she worries that this could complicate their friendship. Later in the botanical gardens, it is discovered someone cut a stalk off the Merriwick and as it declines, it appears the plant is not alone in being affected.

In season three, Cassie (Bell) and Sam (Denton) are officially a couple and will navigate the sometimes-choppy waters that come with their new relationship status, including dealing with the reactions of their kids, Grace (Madison) and Nick (Rhys Matthew Bond). Grace moves further into the high school years and still pushes herself to excel in school while outside the classroom, learns more about her special, intuitive abilities and also feels the first blush of teen romance. Sam works to strike a balance between his duties at the hospital and private practice as well as his responsibilities as a father to Nick and, now, a romantic partner to Cassie. As always, Martha (Catherine Disher), the indefatigable Mayor of Middleton, is working hard to put her beloved hometown on the map and bring it the attention she feels it deserves.
