You and your team planned to spend a quiet night at home, when the doorbell rings. None of you are expecting anyone else to join you. At the door is a box, with no sign of who left it. Inside, there are pictures of some of your other friends bound to chairs – kidnapped.

They’ve left you instructions, the first being not to call the police or tell anyone else what is happening. You must find the money to pay their ransom and save your friends. You have 60 minutes.
