Perhaps Alex's sister decides to visit the prison frequently to support Alex. During these visits, she forms unexpected friendships with some of the inmates. This could lead to her getting involved in some of the internal prison politics or drama, all while still being focused on her sister's well - being. She might also try to work with the prison staff to make things better for Alex.
One possible plotline could be that Alex's sister gets involved in trying to clear Alex's name. Maybe she starts her own investigation into the events that got Alex into prison. She could meet some of Alex's former associates, both the good and the bad, and face various challenges and threats along the way.
Another idea is that Alex's sister discovers some long - hidden family secrets that are somehow related to Alex's situation. For example, there could be a connection between their family history and the criminal underworld that Alex got caught up in. This discovery could send her on a journey to not only understand her sister more but also to potentially find a way to get Alex out of prison by using this new - found knowledge.
