Face of Fear

S6 E7: Hobie's new friend, Isaacs, is a frustrated and angry young kid who will do just about anything to get his distant, workaholic father's attention by trying to swim down a dangerous offshore reef cataract called "the shredder." Meanwhile, Caroline meets Cory, a young horse jockey on the beach whom she encourages to race again ever since he dropped out for an accident. Then things take a turn when an old rival of Cory's pushes him into a grudge horse race at the beach to test the will of the other.
