In this episode of Tech Witch, Bridgette and Lowell journey into the Louisiana swamp to speak with a mysterious necromancer who can help them commune with their deceased grandmother, Grand-Mère Mathieu. Seeking answers about the magical powers they've recently discovered within themselves, the twins make a dangerous deal to have their souls transported to the gray, ashen spirit world while their bodies remain vulnerable back in the physical realm. 

Grand-Mère offers cryptic warnings about the true source of Bridgette's emerging abilities, cautioning that untamed power can flow uncontrolled. Meanwhile, back in the swamp shack, their friend Kylie races to protect the twins' helpless bodies from the necromancer's ravenous hunger. A clash ensues, and when Bridgette and Lowell's souls return, he discovers new depths to his own magical gifts.

With more questions than answers, Bridgette and Lowell leave the swamp changed, marked by their journey to the other side. Their future and the origins of Bridgette's unchecked power now hang in the balance.
