One day a loner kid whose mother is dying and his injured former-firefighter dad abuses him decides to film everything. That ostracizes him more from him peers because he runs around everywhere with some giant camera on this shoulder.
After a party his philosophizing cousin and another friend ask him to film what they found- a large perfectly circular hole in the ground. They jump into it and follow along the cave to find some alien looking giant glowing mineral. Something happens and the the filming is interrupted.
When the filming continues after some time we find them in the backyard controlling a baseball with their minds. Since the incident, they've developed telekinesis. At first with small objects, then larger ones, then themselves. They take their powers public bothering innocent people in stores and parking lots. Then they lean how to levitate and eventually fly.
When the poor loner kid's mom is one the verge of dying, the kid puts on a protective suit and tries to rob a gas station to get meds for his mom. On his way out, the attendant shoots at him; an explosion ensues and the kid catches on fire. He ends up in the hospital. Even there, and after the mom's death, the father will blame him and try to abuse him. The kid loses it completely. Having realized he's an apex predator and that the strong destroy the weak, he's now ready to unleash his powers and destroy all who get in his way. It's left to his cousin to try and stop him.
Chronicle overall has a good idea. It's entertaining to watch the kids develop and tame their powers and experimenting with them out there in the world. The filming is part POV, part third person because fortunately, the kid learns to control cameras and has them swarming around him. Thankfully, even when he has his old camera, the quality of the footage is excellent- unlike those poor bastards in horror movies who are forever condemned to film stuff in dismal quality grainy video. So at least that makes the POV stuff tolerable. But Chronicle retains the weaknesses of that kind of movie. It's boring at times, the portrayal of relationships overall is pretty poor- the relationship between the cousin and some girl is just awful, and eventually you end up with people just screaming at each other. Still, the entertaining aspects outweigh the negatives and this movie offers something we don't see often.
