Marissa's Office Turns Workplace Ambition Into Body Horror in Bite Size Terror

Getting noticed by the boss shouldn't cost you everything. Episode seven of Tubi's horror anthology takes climbing the corporate ladder to disturbing new heights.

Watch Now

You answer the emails. Manage the schedule. Handle the problems nobody else wants to deal with. And somehow, when it's time to recognize all that hard work, your name is nowhere to be found. Sound familiar? Well, Bite Size Terror has a particularly disturbing solution to that workplace frustration.

In Marissa's Office, the seventh episode of Tubi's Original horror anthology Bite Size Terror, an overlooked assistant named Beth is tired of being invisible. Her mysterious boss, Marissa, holds the recognition she's desperate to earn, and Beth is willing to go to unsettling lengths to finally get it. As we explored in our look at the anthology's ten standalone nightmares, ordinary decisions have a nasty habit of turning into something much bigger in this series. Beth's career ambitions are about to become a particularly gruesome example.

The episode takes the familiar pressure to prove yourself at work and gives it a body-horror makeover, turning professional advancement into a dangerous game where getting ahead could mean losing yourself entirely. It's the kind of unsettling story that feels right at home in Terror on Tubi, where everyday anxieties have a habit of becoming full-blown nightmares.

Before we discuss Beth's performance review from hell, a little workplace disclosure: spoilers for “Marissa's Office” are ahead. HR has been notified.

When Getting Ahead Means Giving Something Up

Office politics can be brutal. Being overlooked for a promotion, watching someone else receive credit for your work, or feeling like you're permanently stuck at the bottom of the ladder is enough to make anyone question their career choices. Beth, however, is taking things a little further.

Marissa's approval carries enormous weight, yet the closer Beth gets to earning it, the harder it becomes to separate ambition from obsession. Her boss isn't simply someone she wants to impress anymore. Marissa represents the version of success Beth believes she's been denied, making every interaction feel like another chance to prove she belongs.

The episode also exposes an uncomfortable side of workplace loyalty. Being the perfect assistant means anticipating someone else's needs, staying available, and making their life easier, often at the expense of your own. For Beth, years of devotion have created a dangerous sense of entitlement to something in return. She's already given so much to the job. Why shouldn't she finally get what she believes she's earned?

Of course, horror has a habit of making people regret asking for exactly what they want.

The Price of Becoming Someone Worth Noticing

Climbing the corporate ladder usually involves a little reinvention. A new wardrobe, a sharper attitude, maybe learning to speak up in meetings. Beth's approach to professional development is more extreme.

“Marissa's Office” takes the familiar idea of changing yourself to get ahead and makes it horrifyingly physical. The body becomes another tool for advancement, blurring the distinction between self-improvement and self-destruction. In Beth's world, being qualified for the job may have less to do with what she can accomplish than what she's willing to endure.

There's also something disturbing about the way ambition can make even the most unreasonable demands feel like opportunities. When success appears to be waiting on the other side of one final sacrifice, it's easy to convince yourself the cost will be worth it. The episode pushes that logic into grotesque territory, where the pursuit of a better position threatens to become something far more permanent.

Forget updating your résumé. Beth may need an entirely new job description.

“You wanted to be seen. Now prove what it costs.”

Behind the Bite

Power, desire, and the female gaze are recurring interests in writer-director Chaconne Martin-Berkowicz's filmmaking, and “Marissa's Office” offers a particularly unsettling way to explore all three. Her previous writing credits include Cruel Intentions and I Know What You Did Last Summer, while her short films have screened at festivals including SXSW. 

Rather than treating Beth's transformation solely as a consequence of ambition, the episode also raises questions about who gets to define success in the first place. Her understanding of what makes someone desirable, powerful, or worthy of attention has been shaped by the woman she admires, complicating the distinction between personal ambition and someone else's expectations.

The dynamic becomes even more compelling through Sara Silva and Heather Lind's contrasting performances. Silva brings an anxious vulnerability to Beth, while Lind gives Marissa an almost effortless authority. Their contrasting energies create an uneasy atmosphere where even ordinary workplace interactions carry an underlying tension. A glance, a pause, or an unanswered question can feel just as unsettling as a more obvious threat, allowing the episode's psychological horror to build before its more disturbing elements take hold.
