二十多歲的哥哥們丹與托比，在母親去世後將成為小弟傑米的監護人，丹是容易緊張兮兮且講話不饒人的宅男大哥，托比則是每天追著女生打轉的、瘋瘋癲癲的二哥。個性迥異的三兄弟將如何扶持彼此呢？特別是傑米自從媽媽半年前過世後還沒開口講過一句話？
Brotherhood follows twenty-somethings Dan (Ben Ashenden) and Toby (Johnny Flynn) who become surrogate parents to little brother Jamie (Scott Folan) after their mum passes away. Dan is a sarcastic joker - anxious and a little uptight. Toby is a naive sweetheart with an eye for the ladies. And there is Jamie, the youngest who hasn't said a word in six months since mum’s been gone. Thrust into a new world of responsibility, Dan and Toby are in over their heads. One thing's for sure: the brothers only have each other to rely on since, well, that's all they've got.
