從小熱愛音樂，並最終成爲一名職業巡演音樂人的吉米-泰斯塔格羅斯（朗-埃達德飾），歷經長達25年的時間，足跡遍佈6大洲，帶領自己的音樂團隊巡演幾乎整個地球，他的粉絲、歌迷已然有數百萬之多。如今，已然是中年男人的吉米，終於在45歲這年決定回家，看望自己自20歲父親去世那年便從未見過面的老母親（羅伊絲-史密斯飾），以及他離別多年的小鎮和少時的朋友們。
　　然而，經過多年的歲月洗禮，兩鬢斑白的老母親雖親情依舊，但往日記憶裏的濃情小鎮早已翻天覆地，尤其是多年未謀面的發小、舊友甚至青梅竹馬卻早已是爲人夫婦、情隨世遷。在歷經一番懷舊、追憶、歡笑、誤解甚至打罵之後，無情的歲月與世道之變遷，帶給這位明星顯赫的老搖滾巨星的不僅僅是溫馨滿溢，更多的則是歲月無情和舊愛的逝去。但年邁的老母親多年不變的母子親情卻依舊溫暖如初，她收藏的愛子年少時便盡顯音樂才華時的舊照片和簡報，再次成爲了中年吉米感恩親情、相信生活的動力所在……
　　For over 20 years, Jimmy Testagross has lived his childhood dream: being a roadie for his childhood heroes, Blue Oyster Cult. But the band's Arena-Rock glory days are a distant memory. County fairs and club gigs pay the bills. And Jimmy has become a casualty of these leaner times. With no place to go, no job prospects, and no real skills outside of being a roadie, Jimmy needs to regroup. So he returns to his childhood home in Queens, Ny. There, he revisits old relationships: his ailing, widower mom, a high school crush, a former nemesis and, most importantly, his relationship with himself. Jimmy, the middle-aged man-child, has never grown up. He still carries the resentments and frustrations of his youth, and has allowed them to fester and define who and what he is. Confronted with his mother's illness, Jimmy has a choice: let go of the past and take responsibility for both himself and the woman who raised and now needs him. Or continue to live a life of lies and frustration.
