Research into typical synopsis

Former teacher and recovering alcoholic Jack Torrance (Jack Nicholson) interviews for a caretaker job at the Overlook Hotel in an effort to rebuild his life after his volatile temper lost him a teaching position. The hotel manager, Mr. Stuart Ullman (Barry Nelson), warns Jack that he and his family will be snowbound through most of the winter and of the potential for cabin fever. He drives the point home by recounting a season when the caretaker, Charles Grady, went crazy and brutally killed his wife, his two girls (Lisa Burns and Louise Burns) aged eight and ten, and finally himself. Given his own desperation and the opportunity to pursue his true passion, writing, Jack acknowledges the warning, but accepts the job.

This synopsis of the beginning of "The Shining" gives a description of the location an why the killer in this film (Jack) is the character he has become. It says that he was a recovering alcoholic and he has accepted the job, unaware of how frightening the consequences of taking the job were.

Meanwhile, Jack has chopped his way through the front door and saying "Wendy, I'm home! Danny... Daddy's home!" Jack then knocks politely on the bathroom door. Wendy holds the knife and tries to steady herself as Jack begins chopping down the bathroom door. After chopping away one of the panels, he sticks his head through (in what was to become an iconic moment in horror film history) and screams,"Heeeere's JOHNNY!" Jack sticks his hand through the gap to turn the lock. Wendy slashes at him with a knife, landing a blow to the hand and sending Jack recoiling in pain. Jack continues to chop away at the door until they both hear the low rumble of an approaching snow cat engine. He stalks out.

This is one of the most iconic scenes of horror history, when Jack pokes his head through the door and says "HERE'S JOHNNY!". This was effective as he has a very unique voice which is seen as terrifying to the audience, and as he is breaking down the door with an axe, this builds up the tension as he is getting closer and closer to the victim.
