A group of Preachers' Daughters are on a mission trip to Cabo San Lucas and they quickly become divided over their different views on Christianity and the temptations surrounding them. Megan feels like the odd man out because of her choice not to drink and the drama escalates when Kristiana confesses something to which goes against everything Cierra believes in.

Cierra's temper becomes an issue when she is made mission leader and wreaks havoc among the group; Kayla starts a battle when she selfishly drinks all the water and the girls gossip behind her back. A new girl arrives, shaking things up among the Preachers' Daughters, and the house will never be the same.

Lolly continues to put the girls on edge when she refuses to go to the mission and goes to the beach instead; tensions flare when Lolly brings random guys back to the house and the other girls decide to kick them out and tell Lolly she needs to step up her game. Later, Lolly starts a big fight with Cierra and Kristiana.
