When Josh Handleman returns home in the midst of a messy divorce to bury his estranged father, he gets the shock of his life: his frugal dad was filthy rich. Abe Handleman donated millions to charity, invested in the dreams of Josh's friends, and shared his home with a strange vodka-swilling Russian. Apparently, Abe collected diamonds, too. When Josh can't find them he begins to wonder if his dad's death was truly an accident, and resolves to find his dad's stash.
