This is for those afraid to find themselves amidst the chaos
For those whose dreams rely on infected mushrooms
And for those who never thought they could be anymore than the criminal they were convicted of
Believe
This is for the kid left at the gas station curb
and the middleaged man still playing video games
This is for the people that can only live through a fabric of lies
And for the girl who searches for love, but won't love herself
Believe
This is for the washed up teacher trying to sell inspiration imitations
For those blind with sight, fine with melancholy, and enslaved by reality
Believe
Believe in the fantasy.
Believe in the truth that there is something more
Believe that you could step out of the door and become new
Believe that it is not too late for you
...Believe

Haven't you ever thought about living the dream?
Haven't you ever wandered if there was something more?
I have

I've though about it so hard that's all I think about now

But you don't seem to
It seems you're just fine with life
And that blows my mind the most

Troubles riddle the Earth into ruins
The always will
But you never let it show
Never let the curtains open

How?

How can one hold all of that in?
Wouldn't sanity slip away so easily?
Perhaps just dust in the wind

But what does that make me?
A turning of a page?
An obstacle? What?

I keep forgetting to remember that it all doesn't really matter
I keep forgetting that you want me to be here for you
And just because of that, the future shouldn't matter

But I find myself wondering if you're just wandering
Am I wandering with you?
Pssshhh! When will we own ourselves completely?

...What's the fun in that?
The light is truly just living in the moment
I know that, but why don't I believe it?

You know what, I will wander with you
And tonight will not be the last night I see the light!

Film Analysis

Ordinary World
Young Triston tries to woe his girl with flowers, unfortunately fails, gets laughed at, and gets hit around a few times. "You were always useless at fencing Triston...In fact, I'm having trouble remembering if there was anything you were good at." Then the next day the chick takes advantage of him and gets him fired at his job. "Father, I lost my job." Basically, the town loser.
Call
The king in Stormhold challenges his sons to a competition to be heir to the throne. "Only he of royal blood can restore the Ruby, and the one of you that does so shall be the new king of Stormhold." For some reason that ruby hits a star out of the sky and sends it tumbling to Earth. Triston and Victoria see it and he promises to retrieve it for her. "Victoria, for your hand in marraige, I'd cross the wall and bring you back that falling star."
Refusal
He gets beat up by the old man guarding the wall. "Nobody crosses the wall you know that...Off you go."
Tests Allies and Enemies
Triston's parents help get him to the star with a magical candle. He finds the 'star' and chains her to him, then they begin their journey back. Meanwhile a witch goes on a hunt for the star to cut out her heart and eat it, to get younger obviously. And the two princes that are left also hunt for the star. The Star gets escapes from Triston and he has a vision to go save her. He teams up with one of the princes and walks right into the witch's trap. The Prince doesn't make it. But the magical candle saves the star and him, and somehow they end up in the clouds. They obviously get picked up by a floating pirate ship that collects lightning in storms. The Captain is a real jerk and threatens to kill Triston and take the star as his own. Fortunately he is quite dainty and was just putting a show on for his manly crew. They fake Triston's death, give him a makeover and pretend he's the Captain's nephew.
Mentor
The Captain teaches Triston how to be a man, various things like fighting, flying floating ships, and slow-dancing. The Star and Triston start falling in love, so of course she grows bright. The captain figures out who she is and warns her. The Captain drops them off and they continue on their journey.
Approach
They're almost a day away from crossing the wall. They try to hitch a ride with an amateur witch. The witch can't see or hear the star, so she turns Triston into a mouse and their on their way. The star bears her heart to the mouse, and Triston hears it. They make out ect. ect. and now it's the next morning.
Ordeal
Triston brings Victoria some of the star's hair, but he learns that once any of the star crosses the wall it turns to dust. Triston's mom barely saves the star from crossing the wall. But then they get taken by the witch to go to her evil lair. Triston shows up at the lair, and meets up with the last prince. The prince dies, but Triston manages to take out the witch's two sisters.
Reward
Turns out that Triston's mom is the King's daughter, and since Triston is related, he restores the Ruby and becomes king, with the star by his side.
Road Back
They travel to Stormhold and are crowned, the movie doesn't actually show them going back it just implies it.
Resurrection 
Turns out those who posses the heart of a star (which Triston did) live forever. They lived to see their grandkids grow old.
Return with Elixir
They use a magic candle to go back to the Star's original home, so now they're both stars. They both live forever with each other and get to watch the world go by.
