In Petunia, Charlie, Michael and Adrian are brothers that are trying, to varying degrees, to be responsible adults in lovingly committed, sexually healthy relationships. But, despite having been raised by a pair of psychoanalysts (or quite possibly, because of it), they lack the proper tools to achieve that. Including parents Felicia and Percy, the Petunias are all, quite spectacularly, failing at normalcy. Complicated emotional triangles, sexual addiction, genitalia-based art work and Ecstasy-fueled evenings are just a few of the components in their domestic makeup.
