Strange things bring people together. Things like a tragic death.

31st December 1999. The cusp of a new millennium. Six friends gather for their traditional New Year Celebration - this year, in a lakeside cabin on the outskirts of Prague. In every group of friends, each has a role. All except Gael that is. The outsider. The one who wasn't there when it happened.

Dhan was the jester of the group, until he disappears, taking part of their future with him. In spite of this monumental loss, the remainder of the group has gathered every other New Year’s Eve since to remember Dhan's death and to celebrate their friendship.

But what if that friendship is built on a lie?

Two decades later, on their final celebration together it's Gael’s turn to organise their reunion and she is determined to uncover the truth of what exactly happened that night 20 years ago. In a snowy chalet on New Year's Eve, she starts asking questions. Old wounds reopen and a dark secret comes to light, sending a shockwave through their lives.

Truth comes at a price.

A character-driven psychological drama told from five different perspectives in both past and present, Odd Numbers weaves a tapestry of mystery, grief, survivor's guilt, lies, secrets and how humans change and evolve over time.
