Wanneer op een dag de jonge en mooie Una onaangekondigd op Ray zijn kantoor verschijnt, worden ze gedwongen hun relatie te herzien. Vijftien jaar eerder hadden de twee een gepassioneerde affaire waarvoor Ray gearresteerd is en gevangen heeft gezeten. Sindsdien heeft hij een nieuw leven opgebouwd voor zichzelf. Una komt nu echter verhaal halen.
Nee, helaas is Una nog niet beschikbaar op Netflix in Nederland.
