Midsummer's Eve, Sweden. A night when the sun doesn't set. A night of drinking and dancing. A night to break the rules.
When Julie finds herself alone on her father's estate, she throws caution to the wind and gate-crashes the servants' party. In the sultry heat of that long, light night, she finds herself in a dangerous tryst with her father's manservant, Jean. What begins as a flirtatious game, as the two vie for power, slowly descends into a savage fight for survival.
