Adam and Jane are three years into a NASA mission that has gone very wrong. Their ship is broken and now they drift between Jupiter and Saturn, finding ways to pass the time as they become more certain that no one is coming to save them. Adam paints, Jane attempts to repair the ship. They argue over what movies to watch. And every day, they dance. One day, Adam poses that maybe they should sleep together. Jane laughs the idea off — why mess up their great dynamic just to add one more (admittedly very fun) activity to their list of time-passing options? Thus begins a friendly, flirty debate about whether they’re better off spending their remaining days as friends or something more.
