“Shrek the Musical" follows Shrek, a grumpy ogre whose peaceful swamp is invaded by a chaotic crew of fairy-tale misfits, thanks to the pint-sized tyrant Lord Farquaad. To reclaim his swamp, Shrek agrees to rescue Princess Fiona from a dragon-guarded tower so Farquaad can marry her. Along the way, Shrek and Fiona bond over their love of gross things, while Donkey keeps things loud and hilarious. Fiona’s secret? She turns into an ogress at night. Shrek crashes her wedding, confesses his love, and they live swampily ever after—embracing love, weirdness, and happily-ever-laughter.
