Part of the The Zack Files series
Locked in a museum, a boy uncovers prehistoric secrets and chaos.
During a routine museum trip, Zack finds himself trapped overnight, unveiling a hidden world where Neanderthals roam and woolly mammoths rampage. As exhibits come to life, Zack must navigate prehistoric challenges and unexpected allies. Can he survive the night and solve the mysteries of the museum's ancient inhabitants?
It seems like a regular field trip to a natural history museum–until Zack gets locked inside for the night and discovers what really goes on in those display cases when no one is watching. A tribe of curious Neanderthals, rampaging woolly mammoths, prehistoric food shortages . . . it’s just another wild adventure for Zack!
