'Game Of Thrones' Season 4 Trailer, Plus New Plot Details

Even as HBO viewers the world over try to recover from last night's True Detective finale, the network would like to remind you that there's another acclaimed, buzzworthy HBO drama coming back up on the horizon. The new Game of Thrones Season 4 trailer opens on a fairly melancholy tone, as Sansa Stark (Sophie Turner) bitterly recounts the horrors that have been visited upon her and her family.

Unfortunately for her but fortunately for us, the rest of the promo — along with some newly released plot synopses — suggest that Westeros' troubles are far from over. Watch the Game of Thrones Season 4 trailer and get some new plot details after the jump.

And here's the synopsis for the season as a whole (via Winter Is Coming).

Encouraged by the Red Wedding slaughter in the Riverlands that wiped out many of their Stark nemeses, the Lannisters' hold on the Iron Throne remains intact ... but can they survive their own egos, as well as new and ongoing threats from the south, north and east? While an unbowed Stannis Baratheon continues to rebuild his army in Dragonstone, a more immediate danger comes from the south, as Oberyn Martell, the Lannister-loathing "Red Viper of Dorne," arrives at King's Landing to attend Joffrey's wedding to Margaery Tyrell, and perhaps act on an ulterior agenda. In the north, a depleted Night's Watch seems overmatched against the inexorable Wall advances of Mance Rayder's army of wildlings, which in turn is being trailed by an even more formidable foe: the undead White Walkers. As if that weren't enough, Daenerys Targaryen, accompanied by her menacing trio of dragons and army of Unsullied, is poised to liberate Meereen, the largest city in Slaver's Bay, which could ultimately provide her with enough ships to sail to Westeros and reclaim the Iron Throne.

HBO has also released shorter synopses for the first four episodes:

Let's all pause a moment to appreciate HBO's knack for understatement. "Joffrey and Margaery host a breakfast" sounds like the most boring plotline in the world, but this being Game of Thrones you know there's going to be crazy amounts of drama (and possibly even some bloodshed) involved.

Game of Thrones Season 4 premieres April 6.
