In Dublin, two couples (Jim and Danielle; Yvonne and Chris) are seemingly living in marital bliss. However, when Chris's behaviour begins to change, Yvonne seeks solace in the arms of Jim, and before long they are in the midst of an affair. When a life-changing secret is later revealed, all four are forced to re-evaluate their lives, their marriages, and their friendships - but can anything be salvaged from the wreckage?
Unfortunately the movie The Delinquent Season is not yet available on HBO Max.
