A scientific time experiment at Ivy University malfunctions, sending The Atom (Ray Palmer) into a cascade of temporal distortions. Time freezes, accelerates, reverses, and loops around him as Ray attempts to stabilize the chronal flux before it spreads across Ivy Town.

During the chaos, opportunistic criminals try to exploit the disturbances, forcing Ray to fight crime while navigating unpredictable time-warp physics. Using his shrinking technology, scientific expertise, and precision combat skills, The Atom tracks the anomaly to its source to prevent a full temporal collapse.
