In a nutshell. The main guy and his wife, hit a rough patch in their marriage and they separated for a bit. During that time, the lead hooked up with his ex (Leann's character). She got pregnant but refused to allow him to see his son. No word yet on why he didn't fight. But now said son is all grown up. A hottie named Blue. And he is now wanting a relationship with his dad. His half brother is not a fan. Gotta have that tension LOL. But at the end of the episode, we found out that Leann's character is ill and needs an operation and she has brainwashed Blue into fake wanting a connection with his dad, when all he wants is to hit him up for $ for her operation. His mother twisted the facts by saying that cap never wanted Blue and preferred his heiress wife. How she believes this lie won't be exposed easily is beyond me.
In the preview, you have the wife going to see the ex and warning her to stay away from her husband--or else. So they have added this soap opera angle that isn't needed. 😏
