Achcham Yenbadhu Madamaiyada
A happy go lucky protagonist tries to embark on a secret road-trip on his Royal Enfield. He has eyes for his sister’s classmate, but constrains himself to open up at a later point of time. On a road trip with his girl as days pass and nights are spent in random strangers’ place, they witness nature’s expanse through its length and breadth.

Krishna (Jayam Ravi) is a happy-go-lucky youth who excels in every field but always does strange and dangerous things to obtain a certain “kick” – a thrill or excitement that he craves. One such activity is secretly double-crossing his childhood friend Dass (Sathyan) while helping him elope. At this point, he meets Nisha (Tamannaah), who is shocked at his recklessness and writes him off as crazy. Krishna sets his sights on Nisha and woos her in a very unorthodox way; he begs her not to fall in love with him. After a host of comical situations involving Krishna’s caring but easygoing parents (Prabhu and Suhasini), local thugs (John Vijay and Mayilsamy), and an ever-present comic relief Jackson (Vadivelu), Nisha accepts Krishna’s love. However, she sets a condition: Krishna must stay in a well-paying job (he had resigned from other jobs due to lack of “kick”), and only then will she agree to marry him. Krishna accepts but soon resigns again for the same reason and tries to hide it from Nisha. When Nisha finds out, she breaks up with him and leaves him for good.
