Ivan Vasilievich has been the head of the Ivano-Frankivskteplokomunenergo communal enterprise trade union for many years.

The chairman of the union is proud of the creative achievements of his staff, but is guided by the principle of “warming people first and then singing”. The heating season makes adjustments to the rehearsal schedule. The workforce is trying to fix outdated pipes while angry consumers storm the hotline. Will a Ukrainian folk song warm
a cold battery?
