Night of the Dolphin

S8 E16: Mitch's old policeman friend, Garner Ellerbee, returns where he recruits Mitch's help him bust a drug smuggling ring after a lifeless dolphin washes up on shore, and they end up putting Neely in danger when she willing agrees to place a tracer on a yacht of a shady man from the beach club she is life guarding at. Meanwhile, Cody tries to help the now-deaf Lani adjust to life without sound, who finds it increasingly difficult and frustrating.
