Sathya is a paramedic with an emergency ambulance service. On the anniversary of his father's death, Sathya and the ambulance driver are to retrieve an old man who claims to be critically ill. The patient, Kailasam, boards the vehicle. His earlier claim to be fighting for his life is not apparent, although he has a heart condition. Kailasam's grumpy and obstinate nature causes trouble to the crew as they journey to find a hospital that suites his needs. Who is Kailasam? What does he want? What is the cause behind his adamant nature? The answers to these questions form the crux of the story. The old man needs to find a hospital that will have him, but it is a long way to go. The only way to find out what the universe has planned is to make the journey, and sometimes the journey is the destination.

Reception
The film received positive reviews from critics. S. Saraswathi from Rediff.com gave the film 3.5 out of 5 stars and wrote, "Like the candy it is named after, Orange Mittai with its sweet and sour moments, is a beautifully narrated film with just the right balance of humour and emotions." Nandita Ravi from The Times of India gave it 3 stars out of 5 and wrote, "Overall, like an orange mittai, the film too is bittersweet. The biggest plus of the film is its run time - a mere one hour and forty minutes, which seems to be more than enough to narrate this interesting story. The film ends on the note that 'the journey is the destination', which about sums up the feeling that you get while watching this film". Baradwaj Rangan writing for The Hindu called Orange Mittai "a quiet ode to the bittersweet life". Hindustan Times gave a 3.5 rating out of 5 stating, "This old-age loneliness tale is a must-see". Behindwoods wrote "What strikes in Biju Viswanth’s Orange Mittai is it is not preachy and there is no melodrama anywhere even if there is scope for one. The humor just glides through and enjoyable". India Glitz wrote "Orange Mittai is a simple feel good movie without much fuss and hype silently will enter into your hearts and leave with a small mark".
