Transcript for Kevin Spacey to appear in court on charges of indecent assault and battery

Back here at home, to Massachusetts, and nantucket island, where Kevin spacey will be in court tomorrow. Facing charges of indecent assault and battery involving an 18-year-old male. Linsey Davis is there. Reporter: On the eve of Kevin spacey's country appearance, a clearer indication of his defense strategy. My confidence grows each day that soon enough, you will know the full truth. Reporter: In his first Twitter post in more than a year, spacey posted this video on Christmas eve. The very same day he was charged with felony indecent assault and battery for allegedly groping a then 18-year-old at a nantucket bar in 2016. Former Boston news anchor Heather Unruh said her son was assaulted. Describing him as "A star-struck, 18-year-old young man, who admits telling spacey he was 23 even though he was just 18." Whether he was over 21 or not, Kevin spacey had no right to sexually assault him. There was no consent. Reporter: According to the criminal complaint, Unruh's son took Snapchat video of the alleged assault, which investigators now have. In audio from a pretrial hearing, spacey's attorney Alan Jackson argues the video does not show anyone being groped. What the video shows is a person's hand make contact with a shirt, correct? Yes. Okay, not any body part. Correct. You don't see any body parts. Reporter: He also says the alleged victim told investigators spacey groped him for about three minutes. If we were to stand and count off three minutes, you would agree, trooper, that's an incredibly long time to have a strange man's hands in your pants, correct? I would agree with that, yes. Reporter: Spacey plans to enter a plea of not guilty, and if convicted, he could face as many as five years in prison.
