The premiere picks up immediately from the massive Season 3 cliffhanger.

The episode opens with Superman (Tyler Hoechlin) and Lois (Bitsie von Krockenberg) getting ready for another day in Smallville. However, things quickly take a turn when a strange energy field appears, causing time to loop. The couple relives the same day multiple times, with slight variations each time. They try to figure out what's causing the loop and how to escape.

WEB-DL (1080p/4K) – excellent visual fidelity, especially for the night scenes and VFX work.
