Cassie and Sam's wedding is just days away in the season five premiere of "Good Witch," and the town of Middleton prepares for this highly anticipated event in "The Forever Tree: Part 1." As Middleton's resident enchantress Cassie (Catherine Bell) works on last-minute wedding preparations, Sam (James Denton) looks for the tree that her ancestor was married under as a wedding surprise. Though skeptical of Cassie's world-traveling foster brother Vincent (Gianpaolo Venuta), Sam invites him to be part of the search. Grace (Bailee Madison) becomes troubled when little hiccups keep popping up in wedding planning, and Nick (Rhys Matthew Bond) finds sudden inspiration to focus on his future when he meets a new girl. Abigail (Sarah Power) opens up to the idea of handing her responsibilities as mayor over to Martha (Catherine Disher), but a handsome stranger puts a wrench in her plans. Meanwhile, Stephanie (Kylee Evans) finds herself smitten by a hospital chaplain.

Cassie invites her friends on a trip to Chicago to help them reconnect; Sam is called in to assist on a surgery.
