The trailer begins with Rex looking up at the stars, saying in voice-over, 'Once upon a time, I had bigger dreams.'

They show flashback footage to Rex as a little girl, watching a space shuttle launch at Cape Canaveral in Florida.

'That's gonna be you one day, Rex,' the young girl's mother says, as Rex adds, 'I know it, mom.' 

'But sometimes, life doesn't always work out the way you planned,' she adds, as we see her as an adult working as a bartender.

A larger man runs up to the bar and says 'Yo you,' and she begrudgingly says, 'Can I get you another drink?' 

She's later seen collapsing on her bed and then partying around a campfire and calling 'last call' at her bar.

She adds in voice over, 'Ten years ago, I got lost, but it's not too late,' as she excitedly tells her friend Nadine (Poppy Liu), 'I'm gonna be an astronaut!' 

'Oh my God... wait, come again?' Nadine says, as Rex happily writes out a letter to NASA, as Nadine reviews the resume she created.

'No, girl, this resume will never get you in... but let's make a few changes that will,' Nadine says, as we see some of the embellishments Nadine makes to the resume including attending MIT, flying fighter jets and even winning a Pulitzer Prize.

Apparently one of the changes was changing her name to 'Dr. Tiffany Simpson,' as she's told she's been accepted into astronaut training.

'I'm gonna be an astronaut!' Rex screams to herself, before she arrives at Kennedy Space Center in Houston for her training.

We get a glimpse at her competition including doctors, pilots and soldiers, as they are all grouped together and told by Rudolph Bolton (Dave Foley) that there is a special name for astronaut candidates - ASCANS - which makes Rex laugh.

Rudolph continues that they will be, 'trained and tested' over the next nine weeks and most of the candidates, 'will not pass.'

Rudolph asks in a meeting if they're sure 'Dr. Simpson belongs here,' as Pam Proctor (Gabrielle Union) says, 'We need unconventional candidates. She built a series of gates to protect the manatees from speedboats!'

Toddrick (Sebastian Yatra) tells Rex, 'When we were kids, you inspired me,' as Rex clearly doesn't know how to react.

Rex calls Nadine, angrily, stating, 'You took out everything about my resume being made up and said it wasn't made up.'

Nadine tells her, 'Get your a** back home before you hurt somebody.'

Rex says, 'I was born to do this! Once you let your dreams out of the box, you can't just shove them back in.'

The trailer ends with Rex in a plane, screaming she can't fly as she actually takes off, adding, 'So is this thing hard to land, or...'
