Derry Girls: The Agreement | Preview (Channel 4)

In this special extended instalment of Lisa McGee's award-winning, candid comedy, we return to Derry one year later, as the gang prepare for their final year of school.

It's the week of the referendum on the Good Friday Agreement, but its timing couldn't be any worse, as the highlight of the year, Erin (Saoirse-Monica Jackson) and Orla's (Louisa Harland) joint 18th birthday party, threatens to be overshadowed.

While the family try to get their heads around the possible outcomes of the vote, the gang realise that they may not be ready for what the future holds.

Derry Girls: The Agreement airs Wednesday 18th May on Channel 4.
