In a forest next to a city, all cats roam happily. Or, most of them. Smoke and his brother Coal, along with their friends Snowflake and Flower, are treated badly by Storm. Storm takes their food and bullies them around. Smoke and Coal need help - or else they might lose their home forever. Smoke and his companions go into the city in search of allies to defeat Storm. They meet new friends along the way and have many adventures, but will they find help? Will Smoke succeed, or will Storm take over?
