The synopsis for Legend of the Guardians: The film follows Soren, a young owl enthralled by his father’s epic
stories of the Guardians of Ga’ Hoole, a mythic band of winged warriors
who had fought a great battle to save all of owlkind from the evil Pure
Ones. While Soren dreams of someday joining his heroes, his older
brother, Kludd, scoffs at the notion, and yearns to hunt, fly and steal
his father’s favor from his younger sibling. But Kludd’s jealousy has
terrible consequences—causing both owlets to fall from their treetop
home and right into the talons of St. Aggies. Now it is up to Soren to
make a daring escape with the help of other brave young owls. Together
they soar across the sea and through the mist to find the Great
Ga’Hoole Tree, home of the legendary Guardians—Soren’s only hope of
defeating the Pure Ones and St.Aggies and to save the owl kingdoms. 

The synopsis for The Next Three Days: Life seems perfect for John Brennan until his wife, Lara, is arrested
for a gruesome murder she says she didn’t commit. Three years into her
sentence, John is struggling to hold his family together, raising their
son and teaching at college while he pursues every means available to
prove her innocence. With the rejection of their final appeal, Lara
becomes suicidal and John decides there is only one possible, bearable
solution: to break his wife out of prison. Refusing to be deterred by
impossible odds or his own inexperience, John devises an elaborate
escape plot and plunges into a dangerous and unfamiliar world,
ultimately risking everything for the woman he loves. (

The synopsis for Monsters: Six years ago NASA divered the possibility of alien life within our
solar system. A probe was launched to collect samples, but crashed upon
re-entry over Central America. Soon after, new life forms began to
appear and grow. In an effort to stem the destruction that resulted,
half of Mexico was quarantined as an INFECTED ZONE. Today, the American
and Mexican military still struggle to contain the massive creatures…
Our story begins when a jaded US journalist (McNairy) begrudgingly
agrees to find his boss’ daughter, a shaken American tourist (Able) and
escort her through the infected zone to the safety of the US border. (
