you can sit all day and watch the world go by...
忘了你自己

扔放在繁忙的北美洲中部…

这只是荒野

但在动物被关起来之前，
But before the animals go into lockdown,
有一件事即将震响 落基山脉
one event is about to stir the Rockies.
这一切都在于大角羊
It's all down to Bighorn sheep.
通常很温顺，但今天，

空气中有一种气味
a scent is in the air.
它把雄性变成了战士

所有的雄性都闻到了气味

这是一个完美的时刻
it's the perfect moment for one creature.
狼獾
The Wolverine.
大多数在这里度过一生，甚至从未见过一次
Most people spend a lifetime here and never even glimpse one.
他以被冬天冻死的动物的尸体为食
He feeds on the frozen bodies of animals killed by winter...
…保存在自然界的冰箱里

His nose can detect food buried 20 feet deep.
其他动物也跟着他，希望能偷一顿饭

狼獾必须行动迅速
The Wolverine has to act fast.

He melts back into the wilderness,
总是在寻找另一个机会
always searching for another chance.
抓住时机至关重要，对于

所有生活在落基山脉的生物来说
all creatures that live in the Rockies.
对于一种独特的动物来说尤其如此
And that's especially true of one unique animal.
群山呼唤我们，
The mountains call us,
但我们不是在云层之上而生的
but we're not built to live above the clouds.
