Ron Langston, stressed while trying to get his hardware store open for business by a certain date, has to pass up particpating in a father/son competition at his son Derrick's school. Grandfather Neb fills in, although Neb has problems of his own dealing with teenage foster son Marcus, who complains that he doesn't know where his real mom (who died of a drug overdose when Marcus was 13) is buried. Neb offers Marcus info concerning his mother and they visit the site where her ashes are buried. Meanwhile, Charlie (Charlotte), wanting to impress at a friend's Sweet 16 party, ""borrows"" her mother's credit card to charge a new dress with plans on returning the dress after the party and having the charge credited back to mom's account without her knowing. However, what she didn't plan on was having someone spill punch on her outfit, making it unreturnable.
