　　本片荣获2010年亚洲奇幻电影节评委会最佳处女作奖。

　　加拿大5名刚参加完婚礼的年轻人驱车返回，在接近美国边境的路段，他们被一辆边境警察的车拦下了，他们命令车辆停下，例行公事检查了ID。这些边境警察看起来很可疑，提问也变得愈加严厉。其中一名年轻人的出身好像吸引了警察们的注意，甚至惹恼了他们。年轻人们都尽量克制着，毕竟五人什么都没做错，除了车灯坏了，除了“被”发现藏有大麻。
　　但紧接着，冲突升级了。其中一名女孩想上车拿药，却被警察阻止了，他们开始凶相毕露。年轻人们都被铐上手铐了。女孩开始反抗，很快就被当场侮辱性搜身。接着警察又怀疑随行的小狗身上携带毒品，就用刀给它开膛破肚。局势开始失去控制，警察开枪了，并将这群年轻人统统拘捕，带到林子深处的一个特殊的牢房里。那里安放着很多铁笼子。而噩梦才刚刚开始。

　　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.
