Poolboy cleaning pool, scoops water snake, gets call from Occult Friend about attack, loads up truck, drive to Occult Friend's lets us see the town. (Music montage)
Poolboy picks up Occult Friend, drive to beach, check out scene, some clues, intro Monster Hunters. Occult Friend in love with Hot Host, Techy & CameraMan follow her like lost puppies. Poolboy is unimpressed.
Back to regular life in Montauk. Town center, diner, Gramps works at Liquor Store(?) [somewhere that will help supply the gang with something to fight off creatures] Monster Hunters Van pulls up, begin asking locals questions, annoys Poolboy, Occult Friend eager to be interviewed. PB & OF engage HH, T/CM. OF vies for HH attention, but aloof PB has her attention. OF and T/CM hit it off, comedic relief. PB & HH have an opposites attract moment.
