This "old-school" family adventure offers thrills and laughs galore! Spending summer break at their father's house, Emma and Brian find a huge egg in a cave near their father's house. It hatches to reveal a baby T. Rex, who they name Caesar. But their discovery is tracked by the sinister Kraven, a dealer in rare animals who steals the poor, hungry creature. Together with their reunited parents, Emma and Brian must sneak into Kraven's lab and rescue Caesar before he's sold to an overseas buyer.
