Sienna’s world shatters right after she uncovers her husband Cameron’s betrayal.

While he’s away on what was supposed to be a routine business trip with his much younger colleague, Lucy, Sienna stumbles upon a hotel reservation on their shared tablet—one room, one bed.

Her heart sinks. It’s the confirmation of every quiet suspicion she’s been trying to silence.

Sienna, devastated and angry, doesn’t know what to do.

But then, a few days later, a desperate call comes in from Cameron.

He’s stranded in a remote area, caught in a sudden snowstorm. Lucy is with him.
