Late night at the office, again

You and your coworker Ava work for a company that has recently bought out by a larger corporation. However, instead of you two acclimating and doing the work of the new company, you are left to work all the files yourselves, but for five times the client count. This obviously leading to many late nights and in some cases just sleeping in your office to finish the work required by the weekend. On the cusp of just quitting your job, one late night you decide to plan something crazy with your coworker.
