There's never a shortage of series revolving around mystery, murder or disappearance but ITV's latest offering, The Reunion, turns the format on its head slightly with flashbacks aplenty, the French Riviera and the unfolding of one fateful night.


The series initially premiered on ITVX but is now set to air on ITV1 and is adapted from Guillaume Musso’s bestselling novel The Reunion, also known as La Jeune Fille et la Nuit.

The cast is led by Ioan Gruffudd (Fantastic Four, Liar) as Thomas Degalais, while the rest of the cast boast a raft of international talent including Ivanna Sakhno (Pacific Rim Uprising) and Grégory Fitoussi (Peaky Blinders, Spiral).
