I need a summary of the first 4 HP movies that will allow me to understand the 5th. Please?

First of all, writing a summary is hard for anyone. Know that I am a very thorough person, so get prepared to read a lot.

Fourteen years ago from the beginning of the fifth movie, a dark and evil wizard called Lord Voldemort ruled over many, grouping followers and bringing fear to the wizarding world. The Dark Lord decided to murder anti-Voldemort supporters one night, killing a father instantly and going for the mother and child. Wishing to do a clean sweep, he killed the mother, who thrust herself before the baby Harry Potter (1 year old) sacrificing herself. Voldemort then turned upon Harry to kill him, but the Killing Curse rebounded upon himself and made him into a phantom, neither alive nor dead. Staying with his uncle and aunt, who hated anything to do with wizards, Harry grew up in depression, until when he turned 11, he found out he was a wizard and would be going to the magical school, Hogwarts. At the end of his first year, he fought Voldemort, who had taken over a teacher's mind and body and defeated him for the time being. Into his second year, he battled Voldemort yet again in the form of a 50-year-old diary from Voldemort's teenage years. He would battle against him as well as a giant snake (basilisk) and barely live to tell the tale. In his third year, rumors of Sirius Black, a person convicted of killing 13 people as well as selling the Potters' whereabouts to Voldemort, escaped from Azkaban (comparable to Alcatraz). Sirius would return to Hogwarts to see his godson, Harry, and Harry learns about his godfather, and that Peter Pettigrew, Harry's friend's pet rat, was an Animagus, able to turn into an animal at will, sold the Potters' whereabouts to Him. In his fourth year, Harry witnesses Death Eaters (Voldemort's followers) come back into the spotlight. Once back at school, Harry is chosen as a champion in the TRIwizard Tournament, believing that someone inside Hogwarts is trying to dispose of him. In the third task of the Tournament, Harry and another Hogwarts champion, Cedric Diggory touch the Triwizard Cup together, instantly being transported to the rebirth of Voldemort in human form. Cedric is killed by Peter Pettigrew who helped him return. The Minister of Magic does not believe this story, however, and is hellbent on not believing Harry, and discrediting him in any way possible, influencing people to believe Harry is mad, and attention-seeking.

Although longwinded, I certainly hope that this will help you in your efforts of watching and understand the fifth movie.
