With her son Jace's father out of the picture, Jenelle relies heavily on her mother Barbara. The two have an explosive relationship, which is amplified by the fact that Barbara now has permanent custody of Jace, while Jenelle has limited visitation. Through it all, Jenelle struggles to prove herself as a mom and responsible adult, but her party girl ways keep leading her down the wrong path. When Jenelle and Kieffer get arrested, she must choose between changing her ways or continuing on a downward spiral that could quickly hit rock bottom.
