Four friends, a terrible secret, and one week to stay alive...

Grace doesn't have a family. That was taken away one dreadful day when she was just six, and her twin brother Peter was killed. Instead she has her best friends and flatmates – Jasper, Franklin and Aaron – and nothing can tear them apart.

Living in London, and trying desperately to make a living, the four friends are rapidly running out of money and hope. So, when they find a discarded suitcase in a skip, they can't believe their eyes when its contents seem to answer all their prayers.

But then there is a knock on their door, and a very disgruntled thug with revenge on his mind, gives them one week to return his belongings, or they will pay with their lives. Soon the fractures in their friendships begin to show, and when one of them ends up fighting for his life, the stakes are raised even higher.

Will any of them get to the end of the week alive, or will the best of friends become the deadliest of enemies...
