The Beachcombers

The Sea is Our Friend (2x7)

Air date: Nov 04, 1973

Nick's legs are trapped beneath a monster log on the beach. As the tide rises, the boys fight to extricate Nick, but when brute force fails, imagination succeeds. They fit up Nick with Oesse's mask and snorkel, and then it is Nick's turn to fight panic as the water rises over him and floats the log free.
