Hal works for Bert. Hal is about to be downsized and probably lose Hannah, his wife.
Brooke, Bert's wife, has two choices, she can accept a field assignment which should lead to advancement or she can take a layoff, with jobs very hard to find.
Hal and Brooke can work at the same field assignment, while Bert and Hannah stay in the city.
The four then decide to try a year-long partner swap and become the Swappernauts!
