He and his fiance Jill stumble upon a mystery at the Ruby Club, where Neal's pal, guitarist Paul Starr is wondering where the hell his pianist, Boppy Gates, is. Then Boppy stumbles in, soaking wet, saying "I was thrown into the river and left for drowned!" and announces he's out of Paul's trio and exits. The trio's singer, Avalon Ayres, is crazy about Boppy and totally distraught, so Neal volunteers to find out what's going on.
Turns out his Boppy and another musician, Riverboat Davis, were threatened by song publisher Harry Jefferson, the uncle of Neal's fiance. Davis and Gates knew the truth that Jefferson stole the fortune left by his brother to finance his music business. Jill was about to find out since her 21st birthday was coming up. Valentine saves Jill from Jefferson just in time, and Jefferson confesses and prepares for jail.
