The Colonel sends Eric and Annie a gift--an RV--prompting Eric to talk Annie into taking the family on a trip to see America, and the list of traveling companions grows by the minute. In the middle of the happy madness, Lucy and Kevin make an announcement.
Annie rushes her husband to the hospital when he wakes up with a certain hunch about his heart condition. The kids are a bundle of nerves--especially Lucy--since they don't know whether the news is good or bad. While sitting around in the waiting room, Ruthie and T-Bone decide to get back together, but an unexpected twist of events brings back unresolved issues with the guy who broke Ruthie's heart a year ago.
With plans for another child, Lucy tells Kevin that it might not be a good idea to move so far away from the rest of the family. T-Bone confides to Eric that he's having second thoughts about breaking up with Ruthie, who is spending all of her free time lately with her former crush, Martin. Sandy's boyfriend surprises her with a marriage proposal, and T-Bone's estranged father shows up on the Camdens' doorstep.
Ruthie gets a text message from what she thinks is T-Bone breaking up with her. But the truth behind the matter is a bit different. Meanwhile, Lucy and Kevin try to decide whether or not they will relocate to Crossroads.
Ruthie tries to hide her tattoo from her parents, not realizing that they already know something's up with her. Lucy knows about the tattoo, but she has a very specific reason for keeping it to herself. As it turns out, most of the Camdens have dirty little secrets that they'd rather not reveal...
Eric and Lucy tell everyone that they're going out of town on "offical church business," which isn't exactly true, while Annie and Kevin seek the truth about their spouses' little white lies. Meanwhile, Sandy takes over Lucy's teen class for the day, and Ruthie will do anything to prove that she is not a little girl anymore.
When Ruthie and T-Bone work on a school assignment about the genocide in Darfur, they get the whole Camden family, and the community involved in the cause.
Eric takes a new approach to counseling members of the church. T-Bone stuns Ruthie by telling her what he really thinks of her selfish and obnoxious attitude, then ending their argument with a kiss.
When the paramedics are called to the house, Annie realizes that Eric has been hiding his health issues from her, even though he insists he's fine. Meanwhile, Lucy contemplates having more children after visiting with Sandy, who has problems of her own when she must choose between the two guys in her life.
