As far as radical reality TV experiments go, Seven Year Switch sits towards the top. Like, the very top.

Watch as four married couples facing extreme relationship trouble take to the remote island of Ko Samui, Thailand, to try and save their marriage.

Each couple spends two weeks apart, in luxurious villas dotted across the island. However, the husband is joined by another wife, and the wife plays vice verse.

If you like Wife Swap then you are going to LOVE Seven Year Switch.
