Here's a great shot of Kirsten Baker in the TV series James at 16 (the season prior was titled James at 15) in the 1978 episode "The Gift" as Christina Kolberg. Here's a brief synopsis of the series premise, not that it really went very far.
Here is a synopsis of the episode The Gift; sounds like a winner.James, a daydreamer and photographer, must learn to cope with life as his father moves the family from Oregon to Boston MA. Though there is much humor here, the series dealt with many serious problems (teenage alcoholism, virginity, pregnancy, venereal disease).
James looks forward to his upcoming 16th birthday and hopes to get a car as a gift. His uncle decides to give him a night with a call-girl instead. Shunning that situation, James falls in love with a Swedish foreign exchange student and loses his virginity.
