By chance, Lenny, a young children's book author, discovers a roll of film in an old camera. Curious, he has it developed and is astonished to find that the pictures must have been taken in Prague in 1968, towards the end of the Prague Spring. One of the photos shows a young woman. To find out more about her, Lenny publishes it in a Prague daily newspaper. The effect is disastrous: his family's house is broken into and his father is murdered.
