This is similar to a TWILIGHT ZONE episode "Back There" (Season 2, Episode 13). In that TZ episode, the main character goes to Ford's Theatre to warn everybody about the assassination. In this CBSRMT, our main characters, Mac McDonald (played by William Redfield) & Peg Andrews (played by Jennifer Harmon), replace 2 people in the past to encounter John Wilkes Booth (played by Gordon Gould). In ACT 1, it starts off slow, but the time traveling adventure begins in ACT 2. Then, in ACT 3, that's when things get intense. If you like Ian Martin's writing, you're going to like this one
