Mr. Doctor (1970)

While Mingmueang films his lastest work on an idillic island, the film crew is mistaken for federal agents undercover to observe the movements of local drug dealing. What should have been a smooth shoot, therefore, ends up being bogged down by accidents including a brutal fall from a jeski that leaves his ears ringing. At the hospital, he meets Dr. Namning. With every encounter, they're bound to get into some kind of quarrel. The two clash repeatedly until it's Mingmueang's heart that's in critical condition, not his ears.
