Summer is almost over and Jace isn't happy about starting the new school year... until he meets his teacher, Ms. Merwin. The two fourth grade classes depart for a field trip to the Crystal Lagoon Aquarium, when the school bus breaks down at a National Park near the Lagoon. While eating their picnic lunch, Jace and Rocco's new friend, Mia, disappears beyond the trees. Jace goes to look for her. When he arrives at the edge of the water and finds Mia, he can't believe what he sees!
