The race around Europe starts in the UK for four couples who all have their own relationship issues. With just a map, things get off to a shaky start as the couples start their first challenge.

The race goes to Amsterdam; Hunter gets into deep water with Steph; Rob drops a bombshell; Stephanie suspects Hunter of cheating.

After Stephanie and Hunter's relationship hits breaking point in Holland, they try their best to repair the damage; as the race moves into Germany, things start to look up for singletons Joey and Frida, who are finally working together as a team.

After Stephanie and Hunter spend the night in crisis talks, the cracks within the group remain; as one challenge pushes the boys to make a big decision, a second in Switzerland pushes some of the couples over the edge.

The couples make it halfway through their European road race, and after it all became too much for Hunter and Stefanie, there are just three couples left.

The couples wake up in glamorous Monte Carlo. With Hunter and Stephanie out of the race, a new couple arrives to shake things up.
