Deja vu All Over Again — Larry Brill

At 55, Nate Evans is a washed up Hollywood screenwriter whose life has gone to hell in a hand basket he climbed in to by dumping his high school sweetheart 40 years ago. When he learns Julie Cooper is widowed and working at their alma mater in his hometown, Nate writes a script and follows it to recreate their high school days in hopes of starting his life over. It's the ultimate mulligan....

Except that Julie's fear of growing old alone has her settling to marry her boss.

Except that she rejects Nate for being burned by him when they were teenagers.

Except that she doesn't see her rat fink fiancé is in serious need of finking and Nate needs to torpedo the relationship before she gets hurt, without becoming collateral damage himself.

Except for all that, everything is Groovy.
