They try to find out more about their family and discover the reason for their parents’ death by reviewing the diary of their grandmother, Shahrbanou.
Khanoom Bas' mother believes they are losing their place and value in the lord's house and brainwashes her son (Farrokh, Khanoom Bas' brother) who is rather indifferent to these events into taking action to get rid of Shahrbanou and buy them back their former position and respect.
Farrokh usually travels to the city and spends his time smoking, drinking, gambling and losing money.
After realizing that the lord, who is a father-figure to him and has raised him doesn't love him anymore, decides to take action.
On this path, Farrokh slowly becomes so cruel that he realizes that even his mother and sister don't love him anymore.
