Here is what it's about!
Nuclear Winter is a comedic webcomic taking place in Montreal nine years after a nuclear accident at the fictional Gentilly-3 power plant. The city, though used to rough winters, is now covered by dozens of feet of radioactive snow and under constant assault by meteorological events of unprecendented force. It is in these perpetual snowy settings that Flavie, a ski-doo courrier, makes her daily deliveries, while having to deal with mutated and eclectic urban fauna. Mixing post-apocalyptic sci-fi and historical storms, Nuclear Winter is a story about the complicated, love-hate relationship Montrealers have with winter, in a city that has the some of the most extreme annual temperature changes on the planet.
