Mallory is a young woman minding her own business and reading a book in the park. She sees some mysterious people behind a tree who then run off. On her way home she is convinced she sees herself acting strangely and then also running off - although this is soon forgotten as a different woman frantically greets her like she knows her, says something about "wrong one" and then runs off. She meets the woman again but this time feels like the first time for some reason. The woman introduces herself as The Doctor and is apparently looking for a police box that is invisible; Mallory thinks she is nuts of course but when she is attacked by a creature the Doctor calls the Griffin (an invisible being that feeds off the specular energy residue of time vortexes) then suddenly Mallory is keener to listen to this batty woman.
