When a newly married bride (Samara Weaving) enters the rich, eccentric family (Adam Brody, Henry Czerny, Andie MacDowell) of her husband (Mark O'Brien), she is forced to take part in a fun sanctified by many years of tradition, and this turns into a deadly a game where each participant fights for survival.

In "Burial Game," the stakes are high because the newlyweds are literally fighting for their lives, trying to beat their in-laws in a deadly hide-and-seek game on their wedding night.
Samara Weaving ("Three Billboards for Ebbing, Missouri," "The Guardian") portrays Grace, an engaging young woman from a poor family, seduced by rich Alex Le Domas (Mark O'Brien, "City on the Hill"). Their 18-month affair ends with a wedding on his family estate. The residence is just as impressive as the entire Le Domas clan, headed by Alex's parents, Tony and Becky (Henry Czerny, "Sharp Objects" and Andie MacDowell, "Four Weddings and a Funeral").
 Members of this eccentric family that built a fortune on board games stick together and live in accordance with sanctified traditions. The wedding takes place without major complications, but as part of the party a special attraction is planned for the bride. Grace - still in her wedding dress - unexpectedly joins her new husband and in-laws at a meeting at midnight to take part in the fun they call a traditional family game. As a new family member, he must remove a card from the deck to determine which game everyone will play - because some tension is felt in the air, Grace unwittingly chooses the rare card: "Hide and seek." A few moments after the start of the game, Grace must part with Alex and hide somewhere on the family estate. Others will try to find her before sunrise ...
Soon Grace makes the terrifying discovery that they have become a game in a deadly game. Brought to the limits of her abilities, both physical and emotional, Grace is determined not only to stay alive, but also to change the rules of the game forever, fighting the attackers in all possible ways.
