Larry blames his life's problems on having struck out during a key moment of his state high school baseball championship game on his 15th birthday.
He finds himself still working for the company he had been originally, albeit successful and in a powerful position, and married to the boss's sexy daughter Cindy Jo Bumpers.
He reviews the day he just had, which ended with his getting fired after discovering his department head Niles Pender's scheme to sell the company under the nose of its owners to a group of naive Japanese investors.
Larry leaves the bar, walks home (his car apparently towed), and discovers someone else living in his house, which is now fixed up (previously his yard and driveway were muddy and unfinished).
Mike appears as a cab driver and drives him to his "new" home, a mansion in Forest Hills, explaining that he did in fact hit the last pitch and won the game.
Ellen hates Larry, and he discovers that the union is threatening a walkout due to massive layoffs and increased production since Niles is selling Liberty Republic in both realities.
However, company owner Leo Hansen arrives to deliver a note to Larry, announcing his termination at Cindy Jo's request, and Niles kills him by mistake.
Driven by Duncan to company headquarters, Larry barges into the boardroom, decks Niles, and exposes his scheme just as Leo is about to sign the deal.
Thinking everyone forgot his birthday, Larry returns home (which still has the muddy driveway and lawn) to a surprise party with his family and friends.
[2] Roger Ebert of the Chicago Sun-Times gave the film 2 out of 4 stars and wrote: "The movie is a slow march through foregone conclusions, and its curious passivity is underscored, if that is the word, by the quietest soundtrack I can remember.
