You are the officers and crew of the Maersk Paamiut, the first major shipping line's foray into sending a container vessel through the Northwest Passage. It's high summer 2020, and while there are still risks from ice and unmapped passages and what-all, it's pretty clear which way the wind is blowing... And that wind is hot. Someone has to do it, and it's going to be you.
But this is not a game about manning a container ship in a happy world. Take the current political situation, run it forward to the election in which America's feeble-minded president feels as threatened as he ever has, and recognize that this is a game about a tight-knit competent group of people who will have to rescue themselves from an apocalypse... Because there may not be anyone else left who can.
This is the same game that ran at ACNW 2017, so if you were in that one, no need to be in this also.
