Lisa and Lars have been going through a rough patch in their marriage. They decide to spend some time together at Lars's father's lakeside cabin to patch things up... except that neither intends to do that; they each plan to murder the other for the insurance money! It won't be as easy as either of them think with each gaining the upper hand at times. Then a treat emerges that endangers both of them; Petter, Dave and Roy, a trio of escaped killers were hiding in the attic and now plan to do unpleasant things to Lisa and Lars. Things are about to get nasty.
If you like your comedy pitch black then this is for you. The plot may not have great depth but serves to first put the leads at each other's throats before introducing a threat to them both. The earlier scenes in the cabin are laugh out loud funny. This means when the unpleasantness in the basement starts it is quite a shock as it threatens to go into 'Straw Dogs' territory. The humour does return; much of it at the same time as we witness wince inducing violence. The various weapons employed are quite original as well as guaranteeing a lot of gory damage. The cast is solid; most obviously Noomi Rapace and Aksel Hennie as Lisa and Lars respectively. The setting was great; scenic and remote enough to mean we can believe the activities won't be seen or heard by others. Overall I'd definitely recommend this to fans of gory comedies; it was even better than I'd hoped.
