Sean, along with his children, arrives at his father’s mansion, in which she spent her childhood. She had not been here for a long time and much had changed since her last visit to the house. Now the mansion looks like an impregnable fortress, and even the most perfect prison can envy security measures. She needs to spend only a weekend here, but the very first night will be a test for her. The strangers entered the house and captured her children, demanding to give money that is in the cache of this mansion. They believed that impregnable doors and armored windows would keep Sean from rash actions. But they did not consider what the mother is ready to go to in order to save her children.
