All Fun and Games follows two siblings, 12-year-old Sophie and 10-year-old Max, who are spending their summer vacation with their older cousin, Ethan. Ethan is known for his sadistic and twisted nature, always devising ways to manipulate and torture his younger cousins.
One day, Ethan introduces Sophie and Max to a new game he calls "The Skarrow." He explains that it is a game where they close their eyes and count to ten, while he hides an item somewhere in the house. Their goal is to find the item before the time runs out, but if they fail, they must submit to a cruel punishment.
As the game progresses, Sophie and Max begin to realize that something sinister and evil is lurking in the shadows. They start seeing strange shadows moving around the house, and they hear whispers and eerie laughter that sends shivers down their spines.
As they continue to play the game, more and more bizarre and horrifying phenomena occur. Sophie and Max soon realize that they have awakened a malevolent entity known as "The Skarrow," who preys on the innocent and feeds on their fear.
With their cousin Ethan nowhere to be found, Sophie and Max must put their wits and courage to the test to outsmart and defeat The Skarrow before it drags them into its dark and evil realm forever.
