The story takes place sometime between Star Trek II and Star Trek III. We are introduced to a very emotional Saavik who is having difficulty controlling her emotions. Kirk's son David rendezvous with the Enterprise. Carol Marcus is back at Regula I overseeing repairs to the station after Khan's attack. At a banquet in David's honour, Kirk makes a very uncharacteristically inappropriate toast ("...Long life to our honoured guest and his friends... and confusion to our enemies, the Klingons and the Romulans!").
