The supernatural angle is played well in this early episode of the series, and with a superior cast. Veteran actress Beatrice Straight plays the widow of a distnguished scientist, who may be telepathically transmitting secret information? The catch here is that Soviet agents are listening... The IMF team travels to Austria to sort things out, but instead of the usual cut-throat situations, the team employs a medium, extremely well played by Martine Bartlett as Ariana.
Bartlett gives a stunning performance here (she should have had an Emmy nod), and actually is the whole show, attempting to communicate with a supposedly deceased soul, between thunder and lightning strikes.
This is late night, spooky stuff, well directed and acted. Bartlett, who worked in a number of tv shows and movies, including the iconic SPLENDER IN THE GRASS (1961) opposite Natalie Wood for Warner Brothers, shows her talent. She went on to appear in many cops shows, such as CANNON (three times), with WB aluminus William Conrad.
This is a neat episode for those who like a ghost story, with a pre-EXORCIST slant. This may also have been inspired by the real-life exploits of husband and wife team of spiritualists Ed and Lorraine Warren, who at the time were making headlines across the country.
