all hell breaks loose

Everything goes haywire

A situation suddenly becomes chaotic, violent, or uncontrolled.

The phrase often describes a moment when order collapses: The protest was peaceful until police arrived, then all hell broke loose.

It can also describe less dramatic chaos: All hell breaks loose when the kids get home from school.
