波特(约翰•卓佛塔配音)绝非一只普通的狗。在被女孩佩妮(麦莉•赛勒斯配音)带回家后，波特被她的父亲改造成一只“超级闪电狗”。它有强化的骨骼、风驰电掣的速度、无穷的力量。它要和佩妮一起去拯救被“绿眼人”绑架的父亲。波特靠着它的力量，战胜了无数强敌。
当然，这一切只是在大屏幕上。实际上，波特与佩妮只不过是一起演出一部戏剧。波特并没有什么超能力，但它坚信自己的力量是真实的。一次拍摄后，混淆了真实与戏剧的波特冲出牢笼，要去大街上拯救佩妮，而它无法预知到，它将面临一个没有超能力的真实又危险的世界。

(Wow wow wow...don't let him out, he’s never been off the set before.)
A reality check.
You are part of a TV show; nothing you think is real is real.

Go, nuts, let's see how that works out for you.
Oh, the super barks, scary, scary.

Look, genius, you are not a super dog. (Wow...)
Hehe, the irony. (John Travolta)
What do dogs do?
Most dogs do things like...out of this? But...but...
How do you sleep at night? (Miley Cyrus)
Bolt is lost, he could be anywhere by now.
All you need to do is get from here to there.
There is a guard.
I'll snap his neck.
Whole snap (on November 21)
You are Bolt, you can save the day.
(They are on a cross-country mission. And there is no turning back.)
Let it begin.
It's a good day to die. (Get ready)Initiating escape for adventure.
Nice move. (That’s fully awesome)
