A/N Hey everyone so welcome to the warped mind that is mine to think up the idea that a post-apocalyptic tv show would be awesome to mix in with a movie about aca-nerds. This is my first attempt at writing on here and I know both these fandoms have a lot of support so if anyone is feeling the possibilities of this alternative universe let me know that you want me all to continue with it. This chapter is just a teaser of an introduction and will stick mainly to the show until our Pitch Perfect characters are introduced where it will go from slightly AU to full blown at times. Oh and not all of them will be from the 100, think some will work better as Grounders ;) Without further ado...

Chapter 1 –Time Waits For No One.

What started as one sentence soon became another. The first steps on the ground felt like a new lease of life however all it took was two days for the illusion to come crashing down just like the 100 had. Death was guaranteed to all, no man could escape its grasp. The only question is when. Some of the 100 knew on the Ark they would never last past the age of 18, at least now they had a chance, if they fought for it hard enough, they could survive.

2 Days earlier…

The charcoal stained her hand, seeped into her pores. She stared down at the design below her on the cold hard surface of her enclosure. Every image that surrounded her was an escape from her current solitude. Images replicated from memories in life skills, biology, humanities. Anything she could think of as a reprieve from the despair of loneliness. Two months had already passed yet she knew it would all be over soon. Judgement would be cast in 31 days, happy birthday she thought to herself sarcastically. Deep within she knew the Council would float her. Isolation told her as much. If she wasn't still deemed a threat she would have at least had the small privileges offered to the prisoners.

Loosing herself again in her charcoal dreamscape she was jolted from her thoughts of what it would be like to be on earth, wind blowing through the trees, the smell of the flowers as her fingertips brushed passed them. The lights came to life and the jarring of the door being opened brought her back to reality.

Two guards entered the cell, "Prisoner 319 stand and face the wall"

Quickly getting to her feet Clarke followed the orders and turned her back to the two members of the guard. "What is this?!" she questioned, blood pumping through her body as panic began to seep into every pore.

The lead guard directed her to be quiet, demanding she held out her right arm. Looking behind she saw the other guard unleashing a metallic cuff.

"No, no, it's not my time! I don't turn 18 for another month!" The sound of the electric baton locking into the ready position startled Clarke further. Blood began pumping in her ears and the frantic beat of her heart pounded against her chest.

"Remove your watch." Came the response from the first guard.

Gripping tightly onto the aforementioned object Clarke couldn't believe what was happening, they were early and this was the last object she had to remember her father by. Before they took him from her.

"No it was my fathers!"

If this was going to happen she wouldn't let it go without a fight. As the lead guard moved to remove the watch from her the adrenaline that had been coursing through her system snapped her into focus, springing forward she slammed her hands into the first guard knocking him off-balance. Rounding on the second guard behind her she caught his lead hand holding the baton by the wrist and using her body weight and other hand she pushed his arm into himself, the shock from the baton sending him to the floor. Her feet carried her towards the cell door that had been left unlocked, her haste causing her to crash into the corridor railing. All around her was a similar sight of guards removing prisoners.

The opening of the cell door next to hers jarred her back into action but before she could take off and attempt an escape the voice of the last person she expected to hear reached her.

"Clarke, stop!"

Turing around Clarke was face to face with what she hoped was her last chance at being saved.

"Mom? Mom, what's going on, what is this? They're killing us all aren't they?" She cried falling into her mother's embrace. Abbey quickly encircled her arms around her daughter, holding her for perhaps the last time. "They're reducing population, making more time for the rest of you..."

Stepping out the embrace Abbey quickly cut off her daughter – "Clarke you're not being executed, you're being sent to the ground. All 100 of you." Holding her daughters arms with her hands Abbey saw the pain and fear in her daughters' eyes.

"But it's not safe, no, no!" Clarke sobbed.

"This gives you a chance to live, Clarke. Your instincts will tell you how to survive, just like your father. I can't lose you too. I love you so much." Cradling her daughters face Abbey tried to soothe her daughters fears, it was their only hope for Clarke to possibly survive.

Once again falling into her mothers embrace Clarke couldn't help but feel panic. As her arms tightened around her Mom she felt a sharp prick on her back and a wave of dizziness flood her. The last thing she heard was her mother whispering, "Earth Clarke, you get to go to earth."

The heavy pull against her eyelids was too much but before she submitted to the darkness a flash of red waves caught her attention.
