In season five, love is in the air with Cassie and Sam's much-anticipated wedding, bringing their two families together under one roof to face new challenges as a blended family. Grace and Nick are in their senior year of high school, which isn't without some bumps in the road as they deal with the uncertainty of life after graduation.

In season four, Cassie and Sam are newly engaged and slowly work on wedding plans while trying to subtly help Grace and Nick mend their friendship before tying the knot and blending their families. Cassie continues to impact the lives of her guests at Grey House and works her special brand of magic with those closest to her as well. Abigail is forced to face her past when her long-absent father unexpectedly returns to Middleton. Grace's senior year of high school finds her uncertain about plans for college and brings a bittersweet lesson about life and love. As Cassie and Sam's wedding day approaches, their friends and family turn out for pre-wedding festivities.

In season three, Cassie and Sam 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 and Nick. 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, 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.

Cassie Nightingale, the spirited enchantress of Middleton, is back to her bewitching ways in the second season of Good Witch. For Cassie, this is a year of choices. She and Sam, her handsome and charming neighbor and town doctor, continue to grow closer and question where their friendship will lead them.

Cassie Nightingale, Middleton's favorite enchantress, and her young-teenage daughter Grace, who shares that same special intuition as her mom, welcome Dr. Sam Radford and his son to town. When the New York transplants move in next to the Grey House, they are immediately spellbound by the mother-daughter duo next door, but Sam and Cassie quickly find they may not see eye to eye.
