When a fifteen foot shark lurks too close to his deepsea partner Bert, Eric looks at Skuba diving as more than a reckless thrill. More cautious and adult, he continues to explore the deep. A trip to Baja California where Eric stays with a poor Mexican family, proves to be educational as well as exciting.
