The Cabin Clause

Two bitter rivals. One luxury cabin. Two exes. And a lie that's about to spiral out of control.
Sienna and Julian have spent 4 years trying to outdo each other in the corporate world ever since they were interns. Now, they are both invited to a mutual friend's 'Winter Wonderland' wedding, only to show up and find their exes, who cheated on them with each other, engaged and flaunting it.
When Sienna accidentally blurts out that she's in a relationship with Julian to save face, Julian doesn't correct her. Instead, he leans in and kisses her.
And so, they strike a desperate deal: Pretend to be madly in love for the weekend.
There's just one problem. The hotel is overbooked, and a blizzard is locking them in. To not get caught in a lie, they had to agree to stay in a one-room cabin with - of course - only one bed.
Now, they have to play the perfect couple before the snow clears and they can go back to being enemies. Hence, they draft a contract.
The Cabin Clause
Rule #1: No real feelings.
Rule #2: No crossing the line.
Rule #3: Don't let the exes see you crack.
But between the cabin situation and the way Julian looks at Sienna when no one is watching, the line between acting and reality is starting to blur.
And to Sienna? Julian is looking less like an enemy and more like a permanent distraction.
