Inside the humble castle of Arandelle, built of wood, nestled in a deep fjord. Elsa sleeps in her bed. Her little sister Anna pops up beside her.
"Elsa. Psst Elsa! Psst" Elsa doesn't move. Anna sits on Elsa and bounces on the bed
"Wake up. Wake up. Wake up"
"Anna, go back to sleep" Anna rolls on her back and spreads all her weight on Elsa.
"I just can't. The sky's awake, so I'm awake, so we have to play"
"Go play by yourself" Elsa shoves Anna off the bed. Anna lands butt to floor, sighs, defeated. But then she gets an idea. She hops back on the bed and lifts one of Elsa's eyelids
"Do you want to build a snowman?" Elsa's eyes both pop open. She smiles.
Anna, now wearing snow boots, pulls Elsa by the hand.
"Come on, come on, come on, come on" Elsa tries to shush her, but Anna's too excited.
The girls sneak into the ballroom. Elsa shuts the door.
"Do the magic! Do the magic!"
Elsa laughs and waves her hands together. Snowflakes suddenly burst forth and dance between her palms, forming a snowball. Elsa throws the snowball high into the air. Snow bursts out and flurries around the room. Anna dances about, catching flakes in her palms and mouth.
"This is amazing!"
"Watch this!"
Elsa stomps her little foot and a layer of ice suddenly coats the floor, forming a giant ice rink. Anna slides off, laughing.
Anna and Elsa roll giant snowballs and build a snowman together. Elsa moves his stick arms around.
"Hi, I'm Olaf and I like warm hugs" Elsa speaks in a goofy way
Anna jumps up and hugs him.
"I love you, Olaf"
Anna fearlessly jumps off a snow peak into mid-air.
"Catch me!"
Elsa makes another peak to catch Anna.
"Gotcha!"
Anna keeps jumping. Elsa keeps casting magic.
"Again! Again!"
"Slow down!"
Elsa suddenly slips. Her magic accidentally strikes Anna in the head. Anna tumbles down a snowbank and lands, unconscious.
"ANNA!"
Elsa runs to Anna and takes her in her arms. A streak of Anna's hair that was struck struck turns white.
"MAMA! PAPA!"
The room around them fills with frightening ice spikes. The parents burst through the frozen door. They gasp at the sight of the room.
"Elsa, what have you done? This is getting out of hand!" said the king
The King and Queen rush to Anna and take her in their arms.
"It was an accident. I'm sorry Anna"
"She's ice cold" The queen held Anna
"I know where we have to go"
Carrying the girls, the King and Queen ride their horses out of the kingdom. Snow streams from Elsa's hands, leaving a trail of ice behind them.
A sleepy Kristoff and Sven travel alone through the dark woods. All of a sudden, the King and Queen race by with the girls, leaving the wake of ice.
Kristoff rides Sven as they follow the trail of ice.
"Faster, Sven!"
Kristoff hops off Sven at the edge of a deep valley. They hide behind a rock and peek out. Down below, the King holds a frightened Elsa. The Queen holds the still unconscious Anna.
"Please, help. My daughter!" the king sadly cried for help
Suddenly, a bunch of rocks tumble down the valley toward them. It looks as though they'll be crushed! But, luckily, the rocks stop at their feet. The rocks then unfold, revealing bright faces.
The rock in front of Kristoff wakes up. She grabs Kristoff and Sven by hand and hoof and hugs them close. Sven licks her face and she eyes them both.
"Cuties. I'm gonna keep you" said Bulda, the troll
Back below, the crowd parts for a troll as old as the Earth. They call him Grand Pabbie. He approaches determined. He nods respectfully to the king.
"Your Majesty, born with the powers or cursed?"
"Born. And they're getting stronger"
Grand Pabbie motions for the Queen to bring Anna to him. She does. He examines her.
"You are lucky it wasn't her heart. The heart is not so easily changed, but the head can be persuaded."
"Do what you must"
"I recommend we remove all magic, even memories of magic to be safe... But don't worry, I'll leave the fun."
Grand Pabbie pulls out a glowing blue energy from Anna's head. We see her memories floating right above her. Grand Pabbie changes all of her magical memories to ordinary memories - snowy play indoors with the girls in their nightgowns changes to outdoors on the winter fjords with the girls in winter gear. He puts the ordinary memories back in her head.
"She will be okay"
"But she won't remember I have powers?"
"It's for the best"
"Listen to me, Elsa, your power will only grow"
As he speaks, he conducts the Northern Lights to show a silhouette of an adult Elsa creating magical snowflakes.
"There is beauty in your magic... But also great danger"
The snowflakes turn to sharp spikes.
"You must learn to control it"
In the Northern Lights display, the sharp spikes cause human figures to panic and attack Elsa.
"Fear will be your enemy. But don't worry, a certain prophecy says that someone will always be there for you"
Elsa gasps and buries her face in the King's chest. The King wraps his arms around Elsa, protectively.
"No. We'll protect her. She can learn to control it. I'm sure. But isn't this someone her sister?"
"I'm afraid not. That someone is foretold to be a very wise person, regardless of his age"
"Then, in that case, we'll do anything to find that person. Thank you, Grand Pabbie. Farewell"
They go back to the castle of Arandelle.
"We'll reduce the staff. We will limit her contact with people and keep her powers hidden from everyone... including Anna"
Anna rushes to the hall to see Elsa shut the door to her new room. Anna watches, confused and sad.
