A new trailer for season 4 of 'Game of Thrones' has been released on US TV and is now available to be viewed online.
The clip - which is entitled 'Vengeance' - was broadcast ahead of the latest episode of 'True Detective' on HBO on February 16th.
It begins with Arya listing the names of all the people she plans to kill, while her sister Sansa is still grieving for her family.
In a similar vein, Jon Snow calls for justice, however Tyrion says: "If you want justice you’ve come to the wrong place."
The trailer then shows Littlefinger, who questions what should be done to those who have hurt loved ones.
Cersei also makes an appearance, menacingly stating: "The day will come when your joy will turn to ashes in your mouth and you’ll know the debt is paid."
And then Daenerys - whose heart is set on becoming queen - makes a promise to 'rule'.
The trailer ends with the worrying tagline ‘All men must die'.
'Game of Thrones' has proved a smash-hit with TV audiences around the world since its debut on HBO in April 2011.
The fourth season will be largely based on the second half of 'A Storm of Swords'.
This is the third book in George R.R. Martin’s best-selling fantasy series 'A Song of Ice and Fire', which is set on the fictional continent of Westeros.
It will also draw on the fourth and fifth novels in the series which begin - chronologically - at the same time.
'Game of Thrones' season 4 will debut on US television screens on April 6th 2014 and run for ten episodes. UK viewers can see it on Sky Atlantic from April 7th.
