Oscar's Bell

On a father-son camping trip, Duncan starts noticing something watching from the tree line while his dog Oscar strains at the sound of his own bell to chase it. Chris Cronin builds his slow-burn short almost entirely out of near-silence and suggestion, saving its sharpest scare for a last-second twist.
