Hide and Seek

It was a cloudy day, Sam was walking home from school when a van pulled up next to him and pulled him in leaving no trace. There was a man with a mask who asked Sam to pick a card between 2 cards. Sam picks the one on the left and turns it around 'SEEKER' "I see you've got seeker" said the man in the mask. Sam had a confused look on his face. "You will have a whole month to look for everyone in this country. If you find somebody you have no choice but to kill them". The colour in Sam's face was drowned by shock. His hands started trembling as he dropped the card. "W-what" he was terrified. "You have to or else you die within a month" said the man in the mask. The man in the mask had no tone in his voice. ''It's day 1 tomorrow. Everyone in the country has been informed. You will get your weapons delivered to you by tomorrow.'' Sam was speechless and didn't know what to say.
