In Alaska, all manner of entities and monsters cross into our world from other dimensions and Hannah Riker and her team are the gatekeepers. Riker has a personal score to settle, hunting the monster that slaughtered her parents when she was a girl. Neville, Toddy and Melissa McCoy have her back as they follow in the wake of beings dispensing justice and marking their victims. They intervene on a resort where people disappear even during daylight, fend off a tribe of furry humanoids claiming ownership of a valley, and they stumble upon an ancient, unkillable entity bent on the destruction of humanity.
