Mike O'Donnell threw away the chance of a college basketball scholarship for a marriage to his high school sweetheart, Scarlett, based on love and teen pregnancy. Stereotypically, upon reaching his mid-life crisis, Mike finds himself pretty much alone and miserable, passed over for the big job promotion, kicked out by his wife, for moaning their lives away, and his prospects look bleak. That is until one night when a little reminiscing and a mysterious janitor lead to a magical transformation resulting in Mike finding himself, you guessed it, '17 Again'. Initially thinking this is his chance to live his own life over and realise his own dreams, Mike soon finds he has a lot to learn about others, namely, his soon to be ex-wife and his somewhat troubled/troubling teenage kids.
