Of Lessons Lost is the sto­ry of two gen­er­a­tions: the broth­ers Yaakov and Laz­er who resist­ed the Nazis in occu­pied Poland and lat­er made new lives for them­selves in Pales­tine and Amer­i­ca. It’s also the sto­ry of their sons. Avi becomes a colonel in the Israel army. Jonathan becomes a suc­cess­ful Amer­i­can entre­pre­neur. Their lives are very dif­fer­ent, but both are head­ing into a fate set into motion all those years ago in Poland.
