Voldemort's power is growing stronger. He now has control over the Ministry of Magic and Hogwarts. Harry, Ron, and Hermione decide to finish Dumbledore's work and find the rest of the Horcruxes to defeat the Dark Lord. But little hope remains for the Trio, and the rest of the Wizarding World, so everything they do must go as planned.

And then to squeeze as much money as possible out of it, WB decide to split it in half and release the second half next year... still a cool movie though.
Was obsessed with the series a few years ago but I've grown out of it.
