Carl Jenkins was fishing off the coast of the small Welsh fishing village of Ynys Du as a thunderstorm hit . He started to head home when he noticed a green light coming from the supposedly disused lighthouse . Feeling around in his canvas fishing bag , he spiked his finger on the barb of one of his fishing hooks . But as he started cleaning up the blood , he heard a child ' s laughter , and something pulled hard at his fishing line . The source of the laughter was a young boy in pyjamas , who was pointing behind Carl at the thing which had pulled on his fishing line . The thing pulling on the fishing line was a brightly coloured monster covered in spines and barnacles with red eyes and barbed claws . The thing swiped its barbed claws at Carl , leaving behind only a pool of blood . The Doctor ' s TARDIS tumbled through space as the Doctor fiddled with her wiring while Rose Tyler slept on the chair in the control room . Rose started stirring as her dreams took her to a beach in Britain where she saw a laughing child and a fisherman . Then , the thing came out of the water and attacked the fisherman with its barbed claws , killing him with one swoop of its arm . She woke with a start , and a quick conversation with the Doctor established that the TARDIS had experienced a similar dream . The Doctor managed to trace the origin of the dream , materialising on the stretch of coastline which Rose had been experiencing moments earlier . The two travellers explored the coastline , noticing a figure in a white coat had gotten to where the fisherman used to be before them . By the time the Doctor and Rose had made it to the fisherman ' s spot , all that were left of him were puddles of blood ; no body , no fishing equipment . As they left the bloody scene , the Doctor noticed a glimmer of light coming from the abandoned lighthouse , but it was off again before he could investigate . They headed on back to the village to talk to the locals and find some answers . To get the the village , they had to go through a wood where they were attacked by creatures similar to and including the thing which attacked the fisherman in Rose ' s dream . The creatures seemed to not conform to any normal evolutionary process but were rather " thrown together " . They managed to escape the creatures due to their relative smallness making it easier for them to pass through the woods until they reached a cul - de - sac as the wood opened up onto the village . The Doctor managed to prevent the monsters from following them further into the village by setting off all the car alarms in the estate with his screwdriver , the cacophony scaring the creatures away . In the village pub , the Red Lion , many of the locals huddled over their drinks while a village meeting fell into the grip of old arguments . Ali Hardy , daughter of pub owners Beth and Mervyn Hardy , sobbed in her room as she tried to stay awake , to delay the onset of the nightly nightmares . Suddenly , the door to the outside opened and the Doctor and Rose stepped through it . Silence fell on the pub as the patrons spied the strangers , but Beth was hopeful when she heard that one of them was a doctor . Mervyn was less easily pacified , suspicious of the strangers who had managed to walk through the town unharmed . When questioned by the Doctor , he denied the existence of the monsters and told them to leave when he mentioned the fisherman ' s death . Luckily , Ali came down the stairs to see what the commotion was , bringing down a drawing of the monster that Rose saw . This was enough to break the tension in the room and let the villagers talk to the Doctor about what had been happening . It was revealed that the phone lines went dead whenever the monsters appeared , so the villagers couldn ' t call for help , and they scoffed at the thought that the authorities would believe them anyway . So they had managed to fit their lives around the monsters , coming inside at nightfall where the monsters couldn ' t get them . Bronwyn Ceredig then interrupted the conversation , accusing Nathaniel Morton of being behind it all as the monsters only started appearing after he had returned to Ynys Du and taken up residency in the rectory . This accusation was met with anger from the rest of the villagers who called her mad and told her to go away . Apparently she had been feuding with Morton for a while . Eventually , the patrons of the pub returned home , leaving in groups and walking as quickly as they could to avoid being in the open as much as possible . Deciding to visit the rectory and the light house once day had dawned , the Doctor and Rose spent the night in the pub , Rose in a guest room and the Doctor not sleeping as usual . " To be expanded "
