Salt on the Skin (1984)

After a computer operator has been through a painful relationship, he is determined to look the other way every time any interesting woman enters his life. He has his other loves - photography and model planes - to challenge him anyway. However, one day a car breaks down in front of his house, and a young mother with her 10-year-old daughter come in looking for assistance. The daughter is endearing and would make a terrific subject for a photo contest. As both the young mother and the computer operator studiously ignore the flicker of romantic sparks, it is only a matter of time before the flame either grows or is extinguished.
