The night before the operation they are taken hostage in their house by masked men and Yael is given an ultimatum - she must kill the prime minister during his operation or her family will die.

Forced by mysterious captors to kill the Israeli prime minister during his upcoming operation, Yael tries everything she can think of to get the it postponed without putting her family, still held hostage at home, in danger. The kidnappers' plan is put at risk when an angry friend comes to see Eyal about a bounced cheque.

The Danons are still hostages in their own home. With Yael having moved the prime minister's operation to buy the family more time, her captors are desperate to get it back on track. Yael is forced to use her wits to bring the operation forward again. Eyal must deal with his money problems to stop people constantly coming to the house, and cracks are beginning to show in the captors' relationships as a power struggle develops.

The Danon family and the kidnappers are surprised when a soldier turns up at the front door, except for Noa, who has been keeping secrets from the rest of the family.

Yael has to perform life-saving emergency surgery on Eyal. The kidnappers now have the soldier captive in the basement. Adam has to bring his team back into line before Alex jeopardises the lives of one of the hostages.

With Noa's boyfriend still captive in the cellar and Eyal still recovering from being shot, Adam is suddenly called away from the house. Yael uses the hospital records to try to identify him. Assaf strikes a private bargain with one of their captors.

Yonatan is determined to get Noa out of the house, even if it means leaving her parents behind. Yael challenges Eyal about his secret money problems. She finds an ally outside the house but cannot risk anything by telling him she is being held hostage.

Yonatan has succeeded in escaping, but things do not go smoothly outside the house. Desperate to look after his children as well as win back Yael's trust, Eyal risks everything to save Assaf.

Noa has made it out of the house and manages to contact Yael's secret ally. Alex is becoming increasingly unreliable, causing tension among the kidnappers. As Adam's plans begin to unravel, Yael is on the trail of the kidnappers' accomplice at the hospital.

Yael has made enough discoveries about Adam to call his bluff. At the house, Alex has won his power struggle with Adam but gone crazy. Having something on Adam might not be enough for Yael to save her family.
