The only thing better than Steven Yeun is Steven Yeun singing karaoke during a spirited holiday party at a rural police station. This week's installment of Jordan Peele's The Twilight Zone reboot delivers just that and more — and it will make you see the former Walking Dead star in a terrifying new light.

TV Guide's exclusive sneak peek at the chilling hour, titled "A Traveler," teases a fun moment with Yeun's mysterious character, but it doesn't take long to dive headfirst into the psychological terror we've come to expect from the gripping series. As festive partygoers sing along to his rendition of Christmas tune "The Man With the Bag," only an officer named Yuka (Marika Sila) remains skeptical of his presence at the station. However, Greg Kinnear's Captain Lane Pendleton brushes off her concerns about the enigmatic stranger — a move that could come back to haunt him.

The episode centers on the sudden appearance of a mysterious traveler (Yeun) in a jail cell in a small Alaskan town. With no explanation as to who he is or where he came from, it's up to one officer to get to the bottom of things.

See how it all unfolds when a new installment of The Twilight Zone arrives Thursday, April 18 exclusively on CBS All Access.
