Having major writer's block

Hello fellow dnders! I got a new campaign book for yulemas and I have lots of ideas for environments and random bounties but I am lost plotwise. My husband will be running 4 characters, one main and three followers. I suck at coming up with original content. My last campaign was largely based on Alice in wonderland and that was fun as hell. So...any hooks? Any plot ideas? Just anything I can run with throw it at me.
