Tread Perilously starts a month of "promises kept" by finally taking a look at Highlander: The Series with the low-rated episode called "The Zone."

Duncan and Charlie make their way to "The Zone" when Joe alerts them to a possible Immortal organizing the homeless in the economically depressed part of town. Charlie reveals he grew up in the Zone, but it's very little help as the fully human Canaan cultivates a world of crime and inequality despite speaking words of equality and revolution. For Duncan, it suddenly becomes personal and he vows to bring Canaan down.

Erik and Justin review why The Highlander was the romance approved for cis-het boys in the 1980s. They get lost in a conversation about masculinity, action hero quipping, and 80s genre movies in general. The accents of the Immortals also come into question. Erik explains the loss of the "Drunken Idaho" moment in Denis Villeneuve's Dune. He also offers a few thoughts on Eternals. Justin points out the startling similarities between Highlander and the Buffyverse. The pair suggest some different casting decisions for Aliens and Streets of Fire. Colin Salmon gets praised despite not being in the episode and Michael Shanks makes a surprise appearance.
