Stranded on Honeymoon Island (UK)

Davina McCall rings the bell on a one-of-a-kind speed-dating event where single hopefuls get to date a stranger they could end up marrying.

Three more couples get hitched on Honeymoon Island and leap into their stranded life together. But while it’s paradise for some of the honeymooners, one couple fail to ignite, and unwanted visitors threaten to derail another’s early spark.

A mysterious crate sweeps ashore to help the honeymooners get better acquainted. Tensions spill over at the first Couples' Cove, before Davina delivers a dilemma that could change one pair’s fate forever.

The time comes for one couple to flare out of Honeymoon Island, signalling the end of their relationship. Elsewhere, the couples swap partners for the day to gain some valuable insights into their marriages, resulting in a few fiery exchanges on their return.

An intimacy crate washes up to help the honeymooners get personal. And when the couples spend the day apart at beach picnics, some are left reeling from shocking revelations, before a brand new couple jump into stranded life together.

The curtain comes down on Film Fest, but there’s an encore of emotion still to come. The couples split into two groups and head off for days out on separate islands, unaware that castaways – some of whom are all too familiar – plan to gatecrash their parties.

The events of castaway day cause a tidal wave across Honeymoon Island. A crate washes up to give the honeymooners some much-needed support from home, before one husband is left with a shocking decision to make.

The recent flare-up causes suspicion and speculation amongst the remaining honeymooners, and even some of the strongest couples start to feel the strain of stranded life. And at the Couples Cove Masquerade Ball, the arrival of an unexpected guest sends shockwaves through the group.
