The teenager Loomis Crowley (Milo Ventimiglia) is testing the underground game Stay Alive with his friends Sarah (Nicole Oppermann) and Rex (Billy Slaughter). When the game is over, the impressed Loomis finds in the middle of the night Rex and Sarah dead in their room, and his is pushed by a shadow from the staircase, breaking the banister and hanging the same way he died in the game. Loomis's sister Emma gives his games to his best friend, Hutch (Jon Foster), and he joins his friends Miller (Adam Goldberg), Phineus (Jimmi Simpson) and his sister October (Sophia Bush), Swink (Frankie Muniz) and Abigail (Samaire Armstrong) to play the unknown game together. When Miller and Phineus die the same way they died in the game, the survivors disclose that the game is based on the life of the evil Countess Elizabeth Bathory, who was buried alive in the tower of her real state in the Geronge Plantation. With the police chasing them, and after the death of October, the survivors reach the house and try to find the corpse of the Countess to destroy her fiend.
"Stay Alive" is flawed, but it is very entertaining and underrated in IMDb. The story is not scary, but a pleasant adventure with good special effects, the actors and actresses have good performances and show good chemistry. The attitude of the police chasing the teenagers is the flawed and silliest part of the plot, and is simply forgotten in the rest of the story. My vote is six.
Title (Brazil): "Stay Alive - Jogo Mortal" ("Stay Alive - Mortal Game")
