Sam has to make a decision, and either way she’s going to lose.

Samantha is still reeling from her discovery about Andreas and is questioning everything she thought she knew about her former best friend. Before she can figure out what to do, Sam makes another shocking discovery, this time about what really happened between her father and the Kristiansens over fifteen years ago.

Sam is faced with two impossible decisions.

Unfortunately, no matter what she decides, she’s going to lose.
