Sarah and Tom are a married couple in terrible financial trouble. On the brink of losing everything, they've managed to find a buyer for their stylish London home. When their best friends Richard and Beth come round for a final dinner, an uninvited old friend, Jessica, tags along.

After a seemingly trivial argument, Jessica hangs herself in the garden. Tom goes to call the police when Sarah realises if the buyer finds out, the sale will collapse, meaning definite financial ruin for their family. The only solution - to convince Richard and Beth to take Jessica's body to her flat and make it look like she killed herself there. If they're clever enough about it, what could possibly go wrong?
