Best friends Bodil and Isabel tell their husbands that they are going away for a short holiday together but in fact they are each providing the other with an alibi so they can have an assignation with somebody else. When Bodil returns to the house they are staying at there is no sign of Isabel. She informs the police she doesn't exactly tell them the truth about what has been happening. When evidence emerges suggesting Isabel has been murdered Bodil will have a hard time being believed as she starts telling the truth. When their husbands arrive on the scene tensions rise and secrets are revealed.
This Dutch film may follow the formula for the genre, plenty of twists and turns and just about everybody being a suspect at some point, but that doesn't mean it isn't fun and the finale is far from obvious. Many reviewers aren't keen on the acting but I thought it was pretty good; especially from Bracha van Doesburgh who plays Bodil. The location, an isolated house near the sea in Belgium adds to the atmosphere nicely. Overall I wouldn't say this was a must see but it passed ninety odd minutes well enough; worth a watch if you enjoy the genre.
