What's the movie slipstream about?

I'm curious, could you please explain what the movie "Slipstream" is all about? I've heard of it but I'm not sure if it's something I'd be interested in watching. Is it a thriller, a drama, or perhaps something else entirely? And what's the main plot or storyline of the film? I'm just trying to get a better understanding of it before I decide to give it a watch.
