Pod

After receiving a warning not to come to their family lake house in Maine, siblings Lyla and Ed stage an intervention for their brother, Martin, a dishonorably discharged veteran who believes the military has experimented on him. When they arrive, they find that he has descended into apparent paranoid psychosis and claims to have trapped a monster in the basement. Martin explains that he found a pod while hunting in the woods and believes it to be part of a government conspiracy to create artificial, inanimate assassins. Martin subsequently pulled several of his teeth to find what he believes is a tracking device. However, since he destroyed it, he can not prove it to his siblings. When Ed demands to see what is in the basement, Martin refuses to let him and reveals infected scratches across his torso, which he says were made by the trapped creature.
