One day, the progressive Chestnut City lost its colors. Its residents are consumed by stress, tension, and a depressing sense of futility caused by an unprecedented number of problems: roads are blocked by traffic jams, the city suffers from communal issues, and mutual accusations have become commonplace.

An evil genius scientist is behind the troubles that have befallen the city of chestnuts. He is preparing for triumph since Chestnut City is about to be plunged into total darkness.

Dan and Rora, a pair of inquisitive friends, organize their own investigation into the events in Chestnut City. The teenagers discover what the evil genius is hiding and why he has sworn revenge on the city he once loved so much.

The friends strive to save the city, but their cause is hampered not only by the scientist's henchmen but also by the stress. Thus, they cannot do without knowledge of mental health support.

The comic is available on the Diia.Education platform. It was created by the Coordination Center for Mental Health of the Cabinet of Ministers of Ukraine as part of the All-Ukrainian Mental Health Program “How Are You?”, an initiative of Ukraine's First Lady Olena Zelenska, with the support of the United States Agency for International Development (USAID) as part of the project “Building a Resilient Public Health System” implemented by Pact. The comic is part of the Mental Health Awareness Month activities.
