So here's my pitch for the sequel: The principals are still with us: Sissy Spacek, Henry Winkler, Julie Kavner. "The Radical II" finds Henry Winkler's Bob desperate to prove that Katherine wasn't violent and had been set-up by COIN infilitrators. He seeks out her old friends including a squeemish Margot. After he leaves, Margot visits an afluent friend . . . Katherine. She's not dead. She staged her death in the bombing. Since then, she's made herself over into a different person who works for the government and uses her position and prestige to leak documents to WikiLeaks.
"Katherine" is also known as "The Radical" and it's a TV starring Sissy Spacek in the title role as as a woman who wants to teach literacy in Latin America and encounters abuse, class warfare and tyrants close up. She wanted to help and thought this would be a few years and then she'd get married and have children. But the reality of oppression awakens her and radicalizes her as do the times. She becomes a revolutionary bit by bit transforming completely -- like many in real life -- following the police abuse at the Democratic Convention in Chicago in 1968.
After she returns to the US, she takes up with Bob due to shared causes but they break up after the convention because she wants to (her words) "go all the way." He's not really up to that.
And she continues on as a member of the Weather Underground and underground. Near the end of the movie she and other members of the Women's Liberation Wing of the Weather Underground enter a school, take over a classroom and inform the students of their rights. The police arrest them (and beat them) and she's facing charges.
She goes home for a rare visit. Her parents (Jane Wyatt and Art Carney) are having a party with their other daughter's family. Katherine tells her sister about the arrest and that she's going underground for good and won't see her again because she's not standing trial. Art Carney overhears some of it but plays it like he didn't and takes her into the party to have a dance with her.
Then we see Katherine being followed by a man. (Actually, we've seen bits of it throughout the movie but she's got black hair and we might not have realized it was her.) She enters a building and it blows up.
Then we get her friends and family talking to the camera about her one last time. (Julie Kavner plays her friend from college that she used to play poker with.)
This is a really great movie directed by Jeremy Kagan and featuring great performances all around but especially Sissy Spacek. I streamed it on Amazon.
