Jesse has returned home from Greece, where he attended Papouli's funeral, and he has brought his cousin Stavros home with him. What Jesse doesn't know is that Stavros is a womanizing con artist. Stavros swindles Joey out of his watch and $20, makes a pass at Rebecca, gets Danny a $65 parking ticket, and he also makes D.J. pay for an awful-smelling goat pizza with lamb guts that Stavros had the money for all along. When everyone tries to tell Jesse what kind of man Stavros is, Jesse refuses to believe them. However, Stavros arrives and prepares to go home, because he claims that the village of Polopolis was ruined by a severe mudslide. Before he leaves, he reimburses everyone, and apologizes to Rebecca.
Despite that, the Smash Club is the setting for Stavros' final scam, and he is raising money at the Smash Club for Polopolis' recovery from the mudslide. Rebecca and the girls discover that there was no mudslide, and that Stavros plans to use the money for a flight to Orlando later. Rebecca comes up with a successful plan that proves to her husband who Stavros really is, and Jesse bans Stavros from the Smash Club, then apologizes to his family for refusing to believe them. He then decides to donate the proceeds to a children's hospital.
