Escape Plan 3: Devil’s Station Synopsis

It’s been known for some time that Escape Plan 2: Hades had an immediate sequel produced in the can afterwards.  That movie is called Escape Plan 3: Devil’s Station.  Now the synopsis for the movie has appeared on Wikipedia.

“In this installment, the daughter of a Hong Kong tech executive goes missing in what appears to be a routine ransom job. As Breslin (Stallone) and his crew delve deeper, they discover the culprit is the deranged son of one of their former foes, who also kidnapped the woman in Breslin’s life, and is holding her inside the massive prison known as Devil’s Station.”

So we appear to be sort of retreading a method used in the atrocious second movie, where someone close to Breslin is imprisoned, with apparently Breslin trying to rescue them.  Is this a way of hiring a cheap actor to fill out the screen time, then have Stallone come in again in the third act to save the day and engage in the DTV Cameo Con once again?
