It took off where it ended last December with Smaug the dragon which was awoken from his slumber and wreaked havoc on Laketown. Bard, who eventually killed Smaug with the black arrow, led the survivors to the Lonely Mountain, as news of the death of Smaug spread to the rest of Middle Earth. Meanwhile at Dol Guldur, an imprisoned Gandalf was rescued by Galadriel, which brought on a brief battle between Sauron aided by his Ringwraiths and Galadriel, Elrond and Saruman. A corrupted Galadriel managed to cast Sauron and the Ringwraiths from the fortress before collapsing.
Back at Erebor, tension mounted among Thorin and his dwarves as he was afflicted by Smaug's dragon sickness to find the Arkenstone. He ended up distrusting Bilbo and his dwarves and refused Bard's negotiation for peace. A battle was ensuing between Thorin and his dwarves, Thranduil and his army of Elves and Bard and the townsfolk before two other armies comprising Thorin's cousin Dain who led another dwarf army and Azog the defiler and his Orc army all converged together to fight the titular battle. The dwarf brothers Fili and Kili were unfortunately killed by Azog's son and Orc chieftain Bolg during battle. Legolas slayed Bolg to rescue a grieving Tauriel who had a relationship with Kili just as Azog and Thorin killed each other, but not before Thorin mended his relationship with Bilbo before his death.
Peace was restored after the Orc army was defeated and Bilbo, still in possession of the ring, left the dwarves to return home and Legolas took Thranduil's advice and departed in search of the Dunedain Ranger. The movie ended with a 111 years old Bilbo sixty years later, who was reminiscing his past adventures in his abode, receiving a visit from his old friend Gandalf. That marked the start of the other movie series "The Lord of the Rings" that preceded "The Hobbit".
I read that some audiences were disappointed with this movie but I wasn't. I did find it kind of entertaining, I must admit.
