This show, a mini-series of six episodes, was one of the highlights of Swedish Television productions in the mid-70s. The prolific protagonist was played spot-on by Anna Godenius whom we otherwise saw sparsely of. She made a magnificent appearance in this show as the sociopathic female con artist who possesses an amazing capability of altering her looks, speech and demeanour.
Leif Krantz, who previously directed two epic teen dramas (Kullamannen and Kråkguldet, both of them reviewed by me at IMDb) failed somewhat in this production by not introducing the main character properly; we never get to know who she is, what her real name is, etc. She seems to have an accomplice, an air-stewardess with whom she's confident, but that doesn't make much sense to the viewer as the nature of their relationship isn't displayed further. On the other hand, two men trying to reveal her identity (one of them being a cop) makes for a subplot.
There are lots of depressing studio based sequences that bring along the stereotypical cabined feeling of 70s TV.
All in all rather good entertainment, however, especially for nostalgists.
