Plain script is the film, italics are the titles.

Jason rushed to save Becky as Simon tied her to the railroad tracks.  The plucky and handsome Jason yelled at Simon “Turn that damsel loose, or I will thrash you with my mallet.”

The much larger and very ugly Simon reluctantly left with a snarl on his face.  Becky was able to free herself and left as well.

The next day:  Jason found Simon beating on Becky’s door screaming “The rent is due.  You must pay or I will ravage you mercilessly.”

After Simon burst through the door and locked it behind himself, Jason heard Becky screaming from within.  He could not get into her house but vowed “I will comfort that poor maiden later.”

Jason wandered the village aimlessly for a few days without seeing any other assaults on Becky.  He saw neither she nor Simon.

The next Saturday Jason took his usual walk down to Emerson Lake on Palmer Road to enjoy his solitude.  He saw Simon and Becky thrashing in the water.  He yelled to Becky “I’ll save you.”

After wading into the water Jason started to sink.  Becky broke free from Simon and pulled Jason to the shore and then ran away naked.  Simon was no longer visible.

The next day Jason went to Becky’s house.  

Jason said “I’m so sorry that I couldn’t protect you from Simon.” 

Becky replied “Jason, you poor handsome, but simple fool.  Simon and I are kinky lovers.  What you saw at the railroad tracks was an attempt at bondage – sex combined with ropes.  The railroad abandoned the tracks so there was no possible harm.”

The flashback shows kinky sex with ropes on the railroad tracks.

Becky explained “The ‘rent is due’ scene is an example of role playing.  Simon and I enjoyed the poor damsel – villain scene immensely.”

A flashback shows Becky pretending to keep Simon from ravaging her while she screams and giggles.  All of their clothes are torn off.

“Our next attempt at kink didn’t work out.  Sex underwater is just too complicated.”

The next flashback shows two naked bodies partially submerged unsuccessfully attempting sex. 

Back to Jason and Becky.

Jason:  “I’m such a fool.” 

Becky replied “Jason, I’m sorry that we deceived you so cruelly.  There is a way we could make it up to you.  What do you think of you, the hero, being involved in some of the, shall we say, intimate scenes?  Simon has already given his approval.”

Jason smiles.
