Lainey Morgan's life finally seems to have settled after a traumatic past year, and she's in a stable relationship with Nat, her "comfy slippers" boyfriend. But a chance encounter with Kieran, her ex-boyfriend, shakes her world and she finds herself increasingly involved in supporting Kieran through an emotional meltdown. While Kieran struggles with loss and the demands of the music industry, the demons of Lainey's past return to haunt her, and an anonymous enemy undermines her through social media. Drawn together by a bond they thought was broken, faced with deception from unexpected quarters, it begins to seem as if the only people that Lainey and Kieran can trust are each other.
