But his ambitions get a stunning reality check with the arrival of Zack, a raving, 68 year-old drunk claiming to be the boy's older self. Suspiciously unable to recall the exact details, Zack is desperate to avert a single, tiny mistake he claims sent the rest of his years into a tragic spiral. As the two forge a shaky alliance to piece together the old man's fragile memory, Z.T. deals with the pressure from his well-meaning Coach and courts a new love, Delena. After a devastating confession from Z.T.'s father, Zack's visit takes on new gravity. Now one man, split in two by fifty lost years, risks everything to save his future and his past in a perilous race Against Time.
