JasmineLopez and her brother Arjun love exploring the coral reefs around Fiji where their marine biologist parents are stationed. Jasmine already a certified scuba diver dreams of following in her parents' footsteps and wants to help Arjun do the same. Unfortunately her younger brother is sure he already knows everything. That attitude gets them into danger when Arjun drifts too far from the group during a dive and straight into a reef shark.
