Reb Kalman, the matchmaker, comes home on Shabbat to find out that Reb Pinchas has been there. He learns that Reb Pinchas wants him to find a husband from a good family for his daughter Carolina. Carolina, however, is in love with Max, her French teacher. Pinchas finds them making out and is furious and even more adamant that she marry soon. Reb Kalman finds Kuni Lemel as a possible match. It turns out that Max and Kuni are cousins and are identical, except that Kuni is blind in one eye, limps, and stutters. Max plans to act like Kuni so that Reb Pinchas will have his daughter marry Max by mistake. The real Kuni Lemel shows up and has everyone confused.

Kuni Lemel's grandfather, who lives in Brooklyn, says he will give his fortune to the grandson who will move to Israel and marry a Jewish girl. The twin grandsons, Kuni the Orthodox and Moni the secular, compete for the money.

Rabbi Kuni Lemle has just finished a Torah and is going to donate it to a congregation in Cairo. In exchange for the Torah scroll, the congregation in Cairo will give Kuni's congregation some antique coins valued at a million dollars. Kuni's twin brother's bosses hear about it and they make Muni dress up as Kuni so that he will get the coins instead. Muni gives the coins back to Kuni and the movie ends with a bunch of dancing Hassidim.
