What was known at the time as a supporting feature, and now as a b-film, here is something which outdoes many a longer and splashier work. Much of it takes place in and outside a Home Counties telephone box some six decades ago. Teenage Christina who babysits for the owners of a pub is outside the call box to await the 'bus home when the telephone keeps ringing. From some impulse, she picks up the receiver and, despite finding it's a wrong number, she is beguiled into talking with a strange man, a smooth-talking one with whom she agrees to speak again from the box.
Things look set to go badly from there, with a Chorus figure saying as much - played by none other than Dandy Nichols as the 'bus conductress. Which is a contrast with the cavalier way in which her parents treat the situation after she has mentioned it to her younger sister (Janina Faye), a Buddhist-leaning girl who becomes wise to the imminent danger.
Written by Gwen Cherrell, this is not , for most of the time, so much a thriller as an account of the turmoil in the mind of so many who find a part in so unusual a drama. It is difficult to think of anything quite like it, even those in which a telephone figures largely - and, indeed, the earlier broader-based Never Take Sweets from a Stranger in which Jenina Faye also appeared with similar peril.
