Story: Having been away from home for a while, the Doctor's friends stop off in Sheffield to catch up with friends, family, and their on-hold lives. But their happy reunions are derailed by strange encounters. After dinner with Sonya, Yaz wakes up from a disturbing nightmare to find a strange and threatening man leering from a corner of their darkened flat. Ryan's friend Tibo confesses to frightening encounters with the same man, whom Ryan discovers that night looming over Tibo's bed while he sleeps. Meanwhile, Graham — playing poker with his buddies — is jolted by a sudden vision of an alien woman pleading for rescue.

What does the creepy figure want, and how is he connected to Graham's vision? The Doctor is determined to get to the bottom of the mystery, blissfully unaware that she plays a central role in the nefarious plans that are about to be sprung...
