Synopsis
After the ruin of his land in the Battle of Sudden Flame the Man Beren fled into the elvish realm of Doriath. There he met the Elf-maiden Lúthien and they fell in love with each other. Thingol, the father of Lúthien, did not want his daughter to marry a mortal man. Therefore he asked Beren for a Silmaril, one of the hallowed jewels which the Dark Lord Morgoth had stolen from the Elves, as the bride price. With the help of Huan and Finrod Felagund, Beren and Lúthien defeated Sauron and came to Angband, where they stole a Silmaril from Morgoth's crown. The unfinished poem ends when they encounter the wolf Carcharoth at the gate of Angband.
Besides the main story the poem also tells of many events which happened before, like the meeting of Thingol and Melian, the oath of Fëanor, the return of the Noldor, the war of Beleriand and the duel of Fingolfin and Morgoth.
