The Dark Lord Voldemort's (Ralph Fiennes') power is growing, and he now has control over the Ministry of Magic and Hogwarts. To defeat him, Harry Potter (Daniel Radcliffe), Ron Weasley (Rupert Grint), and Hermione Granger (Emma Watson) must complete the work of the late Albus Dumbledore (Sir Michael Gambon) and find the remaining Horcruxes. With little hope for the Wizarding World, the trio must plan and execute their mission carefully if they are to be successful.
