Welcome to Plathville season 4 is almost upon viewers, but the new episodes will show some cracks in the Plath family's foundation. The entire clan has had a rough couple of seasons mainly due to Kim and Barry Plath's extreme views. Their unconventional ideas have left their family in near ruins. Even though Kim and Barry grew up with normal life experiences, their kids were not allowed the same. The Plaths forbade sugar, TV, and outside friends, choosing instead to homeschool all of their children.

Kim and Barry haven't given themselves the best reputation with viewers who find their parenting practices to be concerning. Their views continue to have an impact on their kids and their relationships. Welcome to Plathville season 4 is set to reunite viewers with the controversial family as they seem to be going through some hard times once again.

Kim and Barry have been married for 25 years, and for them, their union works. Barry is the head of the household, and Kim chooses to raise the children. Even though they do seem to complement one another, they come across as odd to Welcome to Plathville viewers. As seen in the trailer, the new season will show the challenges that the older Plaths are going through when it comes to their own love connection.

In the video, Kim suggests that she is not currently happy within her own marriage, noting that things are "different" now. Even Barry, who is usually pretty laid back, notes that their life as a couple has been "rearranged."  Kim also shares that she is ready to be herself and figure out what she wants out of life. Barry feels that his wife may be having a mid-life crisis due to her jarring behavior. It seems both Kim and Barry will need to take a look inside one another to see if they still want their life together.

If the trailer is any hint, the other Plaths are in for a rough ride as well. Viewers are more than worried that the older siblings weren't taught the coping or communication mechanisms to survive relationship issues. The new season will also show Ethan and Olivia Plath working on their strained marriage. Even Moriah Plath's breakup with her boyfriend Max will be featured. Needless to say, the Welcome to Plathville family will have to mend a few broken hearts to get back on track.
