CBS has opted not to pay the Ransom.
The network has cancelled the drama after three seasons. The news that there will be no season 4 was released on the official twitter account:
#Ransom fans: We’re joyful & lucky to have shared these past three seasons with you. Unfortunately, we have to bid the CriRes team farewell. We loved telling stories about strong, smart characters resolving conflicts with words instead of violence. Thank you for watching.
