One of the main characters Stephan comes to Mystic Falls (the setting) and meets the second main character, Elena. Her parents have recently passed away and she is devastated. She meets Stephen and they fall in love. Bonnie, her best friend finds out some astonishing news that changes her life.
They go to a bonfire and things get crazy from there. The characters find out about supernatural creatures and so on forward. We meet Damon, a crazy vampire who kills and learn about the Salvatore past. (Salvatore is the last name of Damon/Stephan)
That is the basic description of season one of the Vampire Diaries. My friend Debbie has got me into it. At first, I was nervous about watching it because as you get into the show scary things do happen. I ended up REALLY liking it.
I hope you get a chance to watch and enjoy!
