Dennis Looks Like a Registered Sex Offender

A nearby prison has just released some of its inmates due to overcrowding. This becomes problematic for Dennis, who looks exactly like one of the ex-cons. Another one of the released prisoners is Mac's dad, Luther. This is an exciting time for Mac, who desperately wants to bond with his father and have the childhood he never got to experience. While Mac tries to bring his parents back together, Charlie tries to break his parents apart when Frank leaves him for Charlie's mother.
