In a small American town in the 1930s, a poor Jewish couple tries to do its best to make a living. Their child, Zekharia, learns soon how to work honestly and how to save money, building his own empire from nothing. Working hard and helping needing people, he turns thirty and realizes it’s time to start a family. He meets the young Elisheva at the synagogue and immediately falls in love with her, so they decide to get married. They have two children, Gavriel and Yacoov. Yacoov moves to Australia; Gavriel marries Rah’el and has a child, Mykhael.
Life goes on and Zekharia becomes old; one day, after his daily walk, he has a heart attack and dies, leaving his family, especially Mykhael to whom he can’t teach all the things he knows.
Now, Mykhael is a teenager and along with his friends, Robert and Cheryl, builds a device for detecting ghosts… and the story becomes exciting, because grandpa Zek somehow managed to come back.
