The Immortal (2000) - 1x17 - Spy vs. Spa- Followmy.tv

While going through some old things of Sara's, she finds a photo of her grandmother from the 40's...posing with Raphael and Goodwin. In flashback, they tell the tale of how they met her. They were investigating a spa rumored to have mystical healing properties just after World War II. Not only is the spa a haven for various Russian and American spy factions, but it is also at the heart of a demon plan to use the waters of Hell to make those who attend the spa become demon-possessed. The two Immortals manage to save the day and pose with Sara's grandmother for a picture at the end.
