God knows how Matthew Perry managed to swindle getting Zac Efron to play a younger version of himself, but that he did in this flick. He plays a man who's life isn't exactly turning out how he wanted and finds himself wishing he could be a teenager again, and voila! The movie Gods make it happen. He returns to high school delighted with life, thinking he is now free from responsibility but turns out he may have grown up more than he thought, and being a teenager again might not be all it's cracked up to be folks. Funny stuff though at times, with 'This is 40' star Leslie Mann playing Perry's/Efron's wife.
