The Sister - Episode Guide

Nathan seems to have it all — a loving wife, a beautiful home and a solid, if unexciting, career. But Nathan has never been able to forget the worst night of his life: a party that led to the sudden, shocking death of a young woman… the sister of the woman who is now his wife. Only he and Bob, an eccentric old acquaintance, know what really happened — and they've resolved to keep it that way. Until one rainy evening, years later, when Bob appears at Nathan's door with terrifying news. They're digging up the woods.

As Nathan worries about the threat posed by Bob, we learn more about young Nathan and Holly's tentative courtship and how this relationship gave both their lives new meaning. It hasn't been perfect: there have been struggles and disappointments — and the dark shadow of Holly's sister's disappearance hangs over them all. But they're grateful for what they have. Nathan worries as Bob becomes increasingly unhinged, unpredictable, and terrifying. Bob is determined at all costs to recover and lay to rest what they buried in the woods. Will Nathan agree to his plan?

Meanwhile, a surprising connection between past and present is revealed. Jackie, Holly's stalwart best friend, was also a detective investigating Elise's disappearance. She even interviewed Nathan and Bob as witnesses. Will she threaten Bob's carefully laid plans?

As Nathan and Bob grimly dig up the woods, the truth about the night that changed everything is finally revealed, and how the mystery of her disappearance continues to haunt everyone involved.

When Holly confides in her best friend Detective Jackie Hadley about Bob's reappearance, the truth niggles at Jackie… Will she connect the dots?

Just when Nathan hopes he has finally turned the page, Bob has another twist of the knife. Now he must decide once and for all what he will do to keep the secret. 

As Nathan confronts Bob, we're given a final poignant glimpse into what he is fighting for. A peek into the deep intimacy that binds Nathan and Holly: how they both mourn Elise — the sister Holly believes is to be lost and Nathan knows is to be gone — and the comfort their love gives both them and their nearest and dearest.
