Four best friends. One of them is dead. Are their secrets safe?

Uni friends Stacey, Paula, Bev and Valentina used to be inseparable until one weekend before graduation when nothing was ever the same again.

Thirty years later, reunited at Valentina's funeral, Stacey receives a letter written by her late friend asking for one last wish... that the three friends go back to where things fell apart and finally bury the hatchet.

As they revisit their old haunts of their uni days and follow a series of clues left by Valentina, their friend's death begins to look suspicious and it is up to them to find out what happened – but they all have secrets to hide.

They say good friends are hard to come by, but when there is so much at stake and someone is lurking in the shadows, how do you know who is a friend and who is a foe?
