Exchanging Vows is a hosted television series with a rotating cast of wedding planners and two new wedding couples in each episode. In each hour-long episode, two couples compete to plan and pull off the perfect wedding. The twist is that they'll plan each other's wedding ­ not their own.

The program is driven by the challenges faced by the teams as they try to decide what type of wedding best suits their counterparts and then try to make it happen. The excitement builds from the beginning of the program when the couples first meet and start trying to figure each other out until the last scene when one of the couples receives the honeymoon prize for planning the most appropriate wedding. The couples are responsible for planning each stage of their competitors' wedding ­ from the invitations to the wedding dress. Viewers can track the participants standing in the competition as the host rates the teams' success at the end of each stage of the wedding plans. Viewers will root for their favourite couple and wait with anticipation for the next challenge and the final weddings.

A wedding planner will join each couple to help them along the way. The planners will offer creative advice, solace, and encouragement but the ultimate decisions reside with the participants.
