汤姆·布莱克（杰夫·布里吉斯 饰）曾是一位叱咤风云的乡村音乐歌手，然而他却在事业的巅峰时期肆意消耗着自己的人生，结婚、外遇、离婚、酗酒、打人……他的公众形象一天比一天恶劣，而民众也给他取了一个绰号：“坏透的布莱克”。多年过去，布莱克已经步入苍老，他也早已忘却了自己当初对音乐的理想与热情。
　　不过，在一位叫简（玛吉·吉伦哈尔 饰）的记者看来，布莱克其实只是在逃避自己，她坚持要帮助布莱克摆脱酒精的荼毒，让他重新在舞台上焕发光彩。布莱克在简的鼓励下，也开始逐渐振作起来，重新拿起了吉他。不过毕竟多年过去，今非昔比，眼下的时代已经截然不同，布莱克如何跟上时代是一个严峻的问题。过去布莱克的弟子，如今的摇滚巨星汤米·斯威特（柯林·法瑞尔 饰）开始扶持自己敬佩的老师父重新走上音乐之路，而布莱克那颗早已冷却的心也在周遭人的热情浇注之下，再次疯狂起来……
《The Weary Kind (Theme From Crazy Heart)》歌词：
Your heart's on the loose
自由的心飘飘荡荡
You rolled them seven's with nothing lose
失无所失又再度上场
And this ain't no place for the weary kind
这里已容不下疲累的心脏

You called all your shots
你想好故事所有结局
Shooting 8 ball at the corner truck stop
自斟自酌于街头饭馆
Somehow this don't feel like home anymore
故乡物是人非不免让人慨叹

And this ain't no place for the weary kind
可这里容不下疲累的心
And this ain't no place to lose your mind
也轮不到你神志不清
And this ain't no place to fall behind
若落于人后请从队尾离开
Pick up your crazy heart and give it one more try
或寻回癫狂再把赌局重开

Your body aches
身心俱疲
Playing your guitar and sweating out the hate
弹起吉他想把悔恨驱赶
The days and the nights all feel the same
昼夜如斯尽皆恍然
Whiskey has been a thorn in your side and it doesn't forget
酒醉无法使你忘却内心呼唤
the highway that calls for your heart inside
反而扎进胸口如利刺一般

And this ain't no place for the weary kind
这里容不下疲累的心
And this ain't no place to lose your mind
亦轮不到你神志不清
And this ain't no place to fall behind
若落于人后请从队尾离开
Pick up your crazy heart and give it one more try
或寻回癫狂再把赌局重开

Your lovers won't kiss
别再妄想爱人的唇间
It's too damn far from your fingertips
它早已远离你的指尖
You are the man that ruined her world
你这毁了她一切的罪犯

Your heart's on the loose
自由的心飘飘荡荡
You rolled them seven's with nothing lose
失无所失又再度上场
And this ain't no place for the weary kind
疲累的心还须另寻他方
