Seven noble families fight for control of the mythical land of Westeros. Friction between the houses leads to full-scale war. All while a very ancient evil awakens in the farthest north. Amidst the war, a neglected military order of misfits, the Night's Watch, is all that stands between the realms of men and the icy horrors beyond.
Ned Stark, Lord of Winterfell learns that his mentor, Jon Arryn, has died and that King Robert is on his way north to offer Ned Arryn’s position as the King’s Hand. Across the Narrow Sea in Pentos, Viserys Targaryen plans to wed his sister Daenerys to the nomadic Dothraki warrior leader, Khal Drogo to forge an alliance to take the throne.
Having agreed to become the King’s Hand, Ned leaves Winterfell with daughters Sansa and Arya, while Catelyn stays behind in Winterfell. Jon Snow heads north to join the brotherhood of the Night’s Watch. Tyrion decides to forego the trip south with his family, instead joining Jon in the entourage heading to the Wall. Viserys bides his time in hopes of winning back the throne, while Daenerys focuses her attention on learning how to please her new husband, Drogo.
Arriving at King’s Landing, Ned is shocked to learn of the Crown’s profligacy from his new advisors. At Castle Black, Jon Snow impresses Tyrion at the expense of greener recruits. Suspecting the Lannisters had a hand in Bran’s fall, Catelyn covertly follows her husband to King’s Landing, where she is intercepted by Petyr Baelish, a.k.a. “Littlefinger,” a shrewd longtime ally and brothel owner. Cersei and Jaime ponder the implications of Bran’s recovery; Arya studies swordsmanship. On the road to Vaes Dothrak, Daenerys finds herself at odds with Viserys.

Incensed over news of Daenerys’ alliance with the Dothrakis, Robert orders a preemptive strike on the Targaryens that drives a wedge in his relationship with Ned. A captive Tyrion helps Catelyn, but receives a cold reception at the Eyrie from her sister, Jon Arryn’s widow Lysa. Sansa is charmed by the dashing Ser Loras Tyrell, a.k.a. the Knight of Flowers. Arya overhears a plot against her father.
Reinstated as the Hand, Ned sits for the King while Robert is on a hunt. Ned issues a decree that could have long-term consequences throughout the Seven Kingdoms. At the Eyrie, Tyrion confesses to his "crimes," and demands that Lysa give him a trial by combat. Joffrey apologizes to Sansa. Viserys receives his final payment for Daenerys from Drogo.
Explaining that the future of the Lannisters is at stake, Tywin presses Jaime to “be the man you were meant to be” as they prepare for battle. Ned confronts Cersei about the secrets that killed Jon Arryn. With the fate of the missing Benjen very much on his mind, Jon takes his Night’s Watch vows, though not with the assignment he coveted. After Ser Jorah saves Daenerys from treachery, an enraged Drogo vows to lead the Dothraki where they’ve never gone before. An injured Robert takes pains to ensure an orderly transition at King’s Landing.
With Sansa's life in danger, Ned makes a fateful decision. Catelyn brokers an unsavory deal with the slippery Walder Frey. Tyrion acquires a mistress and is forced by his father to fight on the front lines. Robb wins his first major victory and captures a prized prisoner.

As Robb Stark and his northern army continue the war against the Lannisters, Tyrion arrives in King’s Landing to counsel Joffrey and temper the young king’s excesses. On the island of Dragonstone, Stannis Baratheon plots an invasion to claim his late brother’s throne, allying himself with the fiery Melisandre, a strange priestess of a stranger god. Across the sea, Daenerys, her three young dragons, and the khalasar trek through the Red Waste in search of allies, or water. In the North, Bran presides over a threadbare Winterfell, while beyond the Wall, Jon Snow and the Night’s Watch must shelter with a devious wildling.
In the wake of a bloody purge in the capital, Tyrion chastens Cersei for alienating the king’s subjects. On the road north, Arya shares a secret with Gendry, a Night’s Watch recruit.
