Supercell (2023) Timeline Explained – Every Event in Order

Bill Brody ignored his wife Quinn's urgent warnings to exit the 'bear cage' because he was obsessed with capturing the perfect storm footage.

Roy and Zane were forced to leave William behind at the gas station because a supercell was forming rapidly nearby and they needed to move the backup van to safety.
