Ten thousand trapped guests. A triple-digit heatwave. Zero power.
When an electromagnetic pulse destroys the regional grid on opening weekend, Liberty Falls Adventure Park instantly turns into a lethal concrete trap. Electronic gates lock shut, roller coasters freeze hundreds of feet in the air, and a massive fire erupts across Main Street.
Retired fire captain Jack Mercer only wanted a peaceful weekend with his sixteen-year-old daughter, Hannah. Now, with temperatures soaring and water running out, they must navigate a panicked crowd and an authoritarian security force that has taken control of the park's remaining supplies.
With no rescue coming from the outside world, Jack and Hannah must rely on analog tools, forgotten maintenance tunnels, and sheer determination to lead a group of survivors to freedom before the park becomes a graveyard.
