Samson sits near the gates of his prison enjoying (ok, that might be stretch) a day off from labor.
A group of friends from his tribe (i.e. very extended family) come over to visit him.
After chatting with these friends for a while, Samson's father Manoa visits him. They chat about Samson's situation, past mistakes, and hopes for a better future. Manoa says he's going to try to have Samson released, but Samson doesn't want him to bother.
When Manoa leaves, a new visitor shows up: Samson's notorious former wife, Dalila.She asks for his forgiveness and offers to free him from prison, but Samson declines to do either and sends her on her way.
Next, Samson has a visit from the Philistine giant Harapha, who seems to show up pretty much just to mock Samson and refuse to fight with him.
He finally leaves too and a Philistine officer shows up ordering Samson to perform in the Philistine theater.
Samson refuses and the officer leaves, not a happy camper.Samson then reflects and decides that he will in fact participate in this Philistine performance.
The officer returns, Samson agrees to perform, and the officer escorts him away.
We never see Samson again.
Instead, we hear a horrible cry from afar and a messenger comes to inform the Chorus and Manoa that Samson has killed himself and the major officials of the Philistines.
