In this movie Akshay Kumar plays the role of an Orinthologist . An orinthologist is a person who studies or is an expert on birds. The movie tells us about the difficulties faced by birds due to cell phone towers and a fifth force. 

Nowadays there are many proofs saying that the radiations from cell phone towers have made the lives of birds miserable. This radiation affects the health of the bird and makes it difficult for them to live. At night certain birds hit the cell phone towers because of which the bird is either injures itself or dies . Certain reports say that birds migrate from one place to other with help of electro-magnetic waves from the cell phone towers , the birds get confused . 

In physics, there are four conventionally accepted fundamental forces or interactions that form the basis of all known interactions in nature: gravitational force, electromagnetic force, strong nuclear force, and weak nuclear forces. Some speculative theories have proposed a fifth force to explain various anomalous observations that do not fit existing theories. The search for a fifth force has increased in recent decades due to two discoveries in cosmology which are not explained by current theories. It has been discovered that most of the mass of the universe is accounted for by an unknown form of matter called dark matter. Most physicists believe that dark matter is some new undiscovered subatomic particle, but some believe that it could be related to an unknown fundamental force. Second, it has also recently been discovered that expansion of universe is accelerating, which has been attributed to a form of energy called dark energy. Some physicists speculate that a form of dark energy called quintessence could be a fifth force.
