To "stay in tonight" usually means for a couple to relax/get take-out food/stay in bed instead of going out to restaurants and bars. But here, the people don't have a choice of going out: they are in prison. The funny part is that the statement implies that they had a choice and are simply selecting this of their own free will when they're not.
