A stranger by the name of Mario knocks on the Ricardo's door and he turns out to be someone they met in Italy. He's in town to visit his sick friend Sam Francesca. The Ricardos and Mertzes think he means a friend in San Francisco and that he's in the wrong place. He doesn't have money to get to San Franciso and won't take charity. Lucy helps him find several jobs so he can buy his ticket and be on his way. He's not very good at anthing except what he did in Italy, he was a gondolier. After a long search, Lucy finally finds Mario a job at making pizzas. Matters are complicated when the group finds out because he's an immigrant, he's not allowed to work in this country. Lucy goes to get Mario and send him on his way to San Francisco. The catch is, the man he was working for makes her work in his place since they had a deal for a full 3 days worth of work for what he paid Mario. Lucy's at her zany best once again as she fights with pizza dough and the pizza oven. Ricky accidentally runs across her while she's slinging pizzas. He demands that she leave the pizza place. They begin to argue and don't notice that the pizza oven is burning.
Back at home, the Ricardos are out money for a pizza oven on top of everything else. There is another knock at the door. It's another stranger. He's looking for Mario and says that he's Sam Francesca. The group is at a loss since they'd just sent Mario off to San Francisco.
