Serija brutalnih umorov pretresa javnost, detektiva Sommerset in Mills pa se nahajata pred na videz nerešljivo uganko. Model, po katerem neznani zločinec izbira svoje žrtve, je prevzet iz biblijskega izročila – eden za drugim umirajo ljudje, ki jih zaznamuje po en od sedmih smrtnih grehov.

As the night progresses secrets and lies force themselves into the light and polite pretensions are dropped. A knock at the door reveals three masked intruders with an agenda of their own. Will their friendship stand the test? Can they survive the night or will their secrets eventually catch up with them?
