Marlon and Stevie see Yvette's fiancé, Demetrius, cheating on her and they disagree whether or not they should tell her. Marlon refuses, claiming they can't break the "man code". Ashley deals with Yvette's new relationship by turning to numerous hobbies. Yvette discovers what is going on and breaks up with Demetrius after he and Marlon get into a fight at her engagement party.
Loosely inspired by the real life of star Marlon Wayans, this update to the classic family comedy centers on a loving (but immature) father committed to co-parenting his two kids with his very-together ex-wife. While his misguided fatherly advice, unstoppable larger-than-life personality and unpredictable Internet superstardom might get in the way sometimes, for Marlon, family really always does come first - even if he's the biggest kid of all.
