The relationship between Home And Away's Rachel and her fiance Tony is set to come under more strain.

The pair are already grieving after the death of their son Jack, and next week Rachel (Amy Mathews) discovers the father of her baby has been slipping out at night.

Rachel follows Tony (Jon Sivewright) after her worries that he's having an affair become too much to cope with - and is horrified to see him meet up with a beautiful stranger.

The medic pours out her heart to Tony's daughter-in-law Martha (Jodi Wright), who rounds on the older man to think carefully about what he's doing to his fiancee.

All is later revealed - but will it end happily ever after for Rachel, or is her love life set for another rocky ride?
