Colonists in a sleep ship are redirected to a different world than what they signed up for and some emergency is cited as an excuse, though they suspect this was planned all along because the cargo contains supplies aimed at cold weather destination.
They start setting things up in the tropics, and are surprised when the entire ocean shifts to innundate the land they were building on. They realize that this is due to tides.
They figure out that they need to live at the high lattitudes to avoid this issue. And indeed, the destination was a scam.
