It's a romantic drama, set in Morocco during World War II. The main character's an American expat who runs a nightclub and is sort of adjacent to everything. Refugees, the resistance, the Germans, they're just all around all the time and he could get involved with any side he wanted. So he winds up with these letters of transit...

[ The plot of Casablanca goes here okay, and he's pretty enthusiastic about it. ]
