On this riff-tastic riff-tackular episode from the Human Trials series, you're advised to strap your seat belts on tight and secure, and hold on for the ride. No emergency exits. This one's like a slice of life. Who really knows where we're all going, except at the very end where everything flashes before your eyes and you realise, only a little too late. Joke's on you. Joke's on all of us. And that's a bigger secret than it appears.
