Every year without fail, middle aged ladies, Grace, Lilah, Celia, Kristin, and Bridget, have an all girls’ beach getaway. Grace finds out her husband is being pursued by the local homewrecker, Dixie Lynn Lee. The ladies rent a room at the seedy Rendezvous motel, lure Dixie Lynn to the beach, and proceed to make her pay for her attempted crime of passion.
While unpacking and settling into the avantgarde Atlantis beach house, Grace finds an article of her husband Preston's clothing in her suitcase. Inside the pocket she discovers a note from the notorious local home wrecker Dixie Lynn Lee asking Preston to consider her salacious proposition. The ladies become consumed with devising a plan to lure Dixie Lynn to the beach to show her the error of her ways.
