A group of thrill-seeking teens set out to the ruins of Action Wonderland, an abandoned amusement park that burned down fifteen years earlier in a terrible accident. This tragedy supposedly killed two brothers, Otto and Emil Von Metzger, who were trapped inside, giving rise to dark urban legends too tempting to remain unexplored.

However, nothing could prepare them for the deadly truth behind those rumours: the brothers miraculously survived and now haunt the park as the feral ‘Terror Twins’, savagely hunting down those foolish enough to enter their lair. Teaming up with a rogue gang of bikers, this unlikely team of high-schoolers and outlaws now face the ride of their life as they fight for survival.
