Miss Frost (Ruth Dunning) runs a boarding house for elderly ladies in a leafy suburb. However, behind the afternoon tea and games of patience is a secret: Frost and all of her boarders are ex-cons! Caldwell indeed is a notorious jewel thief who is still on the run after escaping prison! Frost's "niece" Freda (Joanna Dunham) is due to marry, though Frost still can't tell the girl she is really her daughter.
Meanwhile an ex-fellow con (Gwenda Wilson) arrives at the home and threatens to shop Frost and ruin her cosy little set-up, a deadly mistake to make...
A great little film, a real period piece of Britain as the 1960s begins and before the great changes to come. A gentle film with a hint of menace not far below the surface and very enjoyable.
