When everyone but Spock is exhausted from their space adventures, a shore leave planet starts gaslighting them about some dangerous illusions. But after no one can find the glade and the landing party gets stranded, a Caretaker appears and explains the amusement planet’s safety precautions. How do you know if you can do a bit on your boss? Who is a little like Bruce Wayne but not really? What does Captain Kirk’s snake tattoo say? It’s the episode that approaches the uncanny valley from the opposite precipice with a glade in between.
