In the 1980s Jimmy Rabbitte formed the Commitments, a ragtag, blue-collar collective of Irish youths determined to bring the soul music stylings of James Brown and Percy Sledge to Dublin. Time proves a great equalizer for Jimmy as he's now approaching fifty with a loving wife, four kids, and a recent cancer diagnosis that leaves him feeling shattered and frightened. Jimmy still loves his music, and he still loves to hustle - his new thing is finding old bands and then finding the people who loved them enough to pay for their resurrected albums. As he battles his illness on his path through Dublin, Jimmy manages to reconnect with his own past, most notably Commitments guitarist Liam Outspan Foster and the still beautiful backup vocalist Imelda Quirk.
