Going up.

Only one way to escape the 'devil's playground' prison, and that is going up.

Isa lang naman ang gusto ni serene.. revenge.

Revenge for the death of her bestfriend, Coleen and all she has to do to be satisfied is to kill the ten students behind the murder case of Coleen Dela Cruz.

Mukang sinuwerte naman siya.. kasama niya sa loob ng underground prison ang fourteen prisoners, including the ten students.

Walang pake si serene kung makakalaya siya or mabubulok na siya sa underground prison na yon. All she cares about is getting her revenge.

Pero pano kung on the way may makilala siya na babago sakanya? Someone who fears death and craved for freedom.. a complete opposite of her.

Someone na hindi kayang pumatay unlike her.. will he be able to warm her heart?

Under the earth where this hell like prison is located.. where deaths and killings are a must. Will love bloom?

And where freedom to the outside world is only obtained by..

going up.
