Who are the strangers Wren sees in the mirror? Twelve year- old Wren Ferris thinks the mirror she finds in the abandoned old movie studio will make a good souvenir. Never having known that her hometown of Trenton, Ontario, had long ago been one of the movie-making capitals of the world, she is enthralled by the thought of the old movie stars who might have gazed into that very mirro. Wren is determined to have the mirror, even after she sees the reflection of a strange man standing beside her. A man who isn't there. When her dad hangs the mirror in her bedroom, no one imagines that it will enable Wren to travel backwards in time to the glory days of Trenton's silent film industry.
