Struggling author Wyatt Harrison and his son Riley travel to the quiet, ocean side town of Dinosaur Cove to begin a new life, searching for healing from the recent loss of Wyatt's wife and Riley's mother. Through their sorrow the two are brought together as they stumble into a delightfully unexpected adventure as the unlikely caretakers of lost Pteranadon eggs. Wyatt must recapture his wonder and his belief in the incredible as young Riley struggles to show him the path to becoming like a child again. Together with the help of new friend Dr. Theresa Starr they must find a way to protect the eggs from the bumbling, mad scientist Dr. Victor Vandersaurian who is also after the eggs. The race to reunite the eggs with their mother - if she can be found - will take father and son into dangers they never imagined awaited them in the little town of Dinosaur Cove.
