Professor Erling (Frederic Downs) and his financial backer Victor (John Stratton) build a time machine to snatch objects from the past. But they find a statuette, radio-metrically dated to 5200 AD! When this draws colleague Richard Hedges (Ward Costello) to the island lab, Erling reveals that 20th-century objects put in the machine seem to be “traded” for future objects by some intelligent life. Also stars Joyce Holden. And with Salome Jens (the Female Shape-Shifter in Star Trek: Deep Space Nine).
