Panther Waits at 5.30 p.m.

Teenager Petr doesn't get on very well with his strict father, and when his father sells his beloved female dog Irina, he feels very much alone. He therefore easily falls under the influence of the older boy Panter, who is making money from fraud and theft. He gets Petr and young Fenek involved in his nefarious activities. One day Fenek throws a cartridge under a tram and the explosion causes nasty injuries to a young girl. Petr is present at the explosion and in fact it is he that the people around the tram notice, because he is wearing a white sweater. The incident opens Petr's eyes and he sees that he should not be involved with Panter. He wants to leave the gang, but Panter has no intention of letting him go and so blackmails him, telling him that the police are looking for a boy in a white sweater. Panter urgently needs money and puts pressure on Petr to steal his father's savings book. The desperate Petr doesn't know what to do. Fortunately he has good friends Martin and Jitka. Martin has been concerned about the change in Petr for a long time, has been watching him and noticing Panter's activities. Together with Jitka he manages to prevent the theft and also to show Panter up as a coward. Petr finds his balance in life again and goes back to his true friends, Martin and Jitka.
