According to one Beskydy Mountains legend, if you do a good deed you will see silver trees. Little Ondra knows trees like that. In his family's cottage hangs a picture showing silver firs, a person falling from a height and a watch. In art lessons Ondra paints trees of the same kind. - One day Lojzek Hojgr, a man who climbs fir trees to gather the seeds, comes to see Ondra's parents. Long-ago Ondra's father has had such a job and Lojzek is his long-time friend. Hojgr moves into a half-ruined wood cabin. Ondra's father takes him on a visit to Lojzek and both demonstrate the beautiful but dangerous work of seed-gathering to the boy.
