Michael is unable to run the family after Mary's death, and Vincent who is not sophisticated in financial matters makes a series of bad decisions, and the family goes broke. Anthony's singing career goes nowhere, and with Johnny FOntaine's help he gets a gig in a B-list Mickey Mouse Nightclub somewhere and barely ekes out a living. Kay's husband Douglas dies, also broke, and she moves into a trailer with Connie. Vincent goes back to the street trying to run some cheap hustles and gets killed when he happens to be an innocent bystander where a drg deal goes bad. At the end of the movie, therefore the Corleone family is finally legitimate.
