My Sister is So Gay

Seth, a middle-aged gay man with an inexplicably hot young boyfriend, has his world turned upside down when his homophobic sister shows up. She caught her husband cheating with her best friend that she doesn't realize she's in love with. Enter Loni Anderson as their over-sexed mother determined to sort out her children's lives as long as they keep her glass topped off with vodka.

Seth is shocked when he finds himself engaged to his hottie beau, Beau. Amanda smells something fishy so she's determined to figure out why this hunk would be interested in her old, bald brother. She enlists Seth's bestie, Becca, and at the same time cluelessly crushes on her. Mumsie's only concern is that her boy will be happy, checking to see if his fiancee is a "big slugger".

Mumsie kicks her wedding planning duties as Mother of the Bottom into high gear leaving Seth in the back seat of his own wedding. Amanda continues dowsing Seth with negativity about Beau, and Beau is on to her. Becca introduces Seth to her girlfriend Parker, knocking Amanda for a loop. Parker comes up with a plan to put Amanda's suspicions about Beau to the test.
