Will what happens on holiday ... stay on holiday? And can they learn to live with the consequences?Every year, a close-knit group of friends spend two sun-filled weeks in a Spanish villa. For Derek and Sharonne, Conor and Maeve, Rory and Trish, and Liam, it's the perfect way to end the summer and escape their high-pressured lives in Dublin. No children, no responsibilities, and no distractions. This year, however, the group befriends Agneta and Anna Maria, two women holidaying in a neighbouring villa, and a series of events is set in motion that will shake the group to its very core.As the holiday comes to an end and the friends arrive home in Dublin, life appears to go back to normal. But the deceptions that began in Spain refuse to be buried and infidelities and secrets come to the surfaceAs facades crumble, each of the friends discover who they can trust and who, ultimately, will betray them.
