三百年来，一把红色小提琴在数个国家流浪，与数人的命运紧紧相牵。仿佛有某种魔咒，让人们为这把琴疯狂着迷。
　　小提琴的制造者，是十七世纪意大利的乐器大师（卡路•施齐Carlo Cecchi 饰 ）。妻儿死去，难抑悲伤的他，把爱人的血涂在小提琴上，从此琴就辗转流落到了奥地利。一个练琴的小男孩为了这把琴痴迷，直至倒落在舞台上。
　　小提琴的流浪从未间断，从盗墓者，到吉普赛人，到为之自杀的作曲家波普，再到文革期间上海的一位音乐老师。这期间，无论拥有者是否明白小提琴真正价值，都逃不出它的魔力。终于，有鉴别专家知道了小提琴的秘密——它的外壳染着三个世纪前一位大师的血和泪。

　　Thomas and Marianne, a feuding couple whose relationship has hit a wall, decide to spend a weekend at Thomas’s uncle’s lakeside cottage. This is their last chance to save their relationship, which has been jeopardized by Marianne’s meaningless flirtations and Thomas’s uncontrollable jealousy. As they arrive, a restless yet charming neighbour welcomes them into their house and, realizing that Thomas’s uncle and girlfriend will not be showing up for days, suggests they share the dinner he has prepared. The drunken night that follows – with this man, who might not be who he seems to be, pushing his charms on Marianne – leads to a weekend of blurred emotions and events, where loyalties, guilt and a shared secret will test the young couple’s ability to survive.
　　Along the way, flashbacks shed light on events that unfold, as Demers – who won the prize for Best Canadian Short Film at the Festival in 1999 for Décharge – begins to introduce information about each character in order to build doubt and ramp up the tension. Jaloux is a tour de force in both its European mood and style and its North American subject and nature, a result which could not have been achieved without the self-assured skills of an expert filmmaker.
