In the near future, a retired army officer and Tamil Patriot battles the odds as he pulls together a motley crew of astronauts to help him revive the lost culture of Lemuria on Mars via the first human space mission to the Red Planet. Just as he is about the announce the mission's successful landing to the entire world, he uncovers an unbelievable truth that could throw everything into disarray.

We travel back in time to understand how and why Lambo pulled off one of the biggest hoaxes in history. With a painful heartbreak weighing him down, Lambo is struggling to prove his worth. Will his band of scientists agree to kickstart his dream project – Mars for All?

The motley crew of wannabe astronauts are ready and have assembled in Lambo’s training center to undergo vigorous training under Karuna’s tutelage. Laanya, Meiazhagi, Sivasaamy, Dhana, Nakulesh, and Samyuktha are eager to be the first to land on Mars. But who are they really?

A podcast interview forces Lambo to reminisce about his past love and he dedicates all his achievements to the one who broke his heart. Back in the training center, Sivasaamy breaches protocols during a mission to ‘save’ Meiazhagi’s life.

Ryan, the primary investor for the Mars mission, insists that he wants to be part of the crew so that he can enjoy the fame. Despite his misgivings, Karuna has no choice but to include Ryan in the training. But it doesn’t go down too well with the rest of the crew.

There’s a new member in town - Sambandam, an eccentric assistant joins Lambo’s team. He seems to be the perfect crony to Lambo but is there more to him than meets the eye? Things get heated up between Karuna and Ryan but the latter wins the moment by flashing his financial influence to the project.

Karuna tries to explain to Laambo about the difficulties of the mission with the crew being totally unprepared. Lambo ignores the warning and insists that Karuna continue with the plan. Laanya and Samyuktha build a better bond with each other while spending time on ‘Mars’ via a VR simulation exercise.

Sivasaamy fulfills his dream of cooking biryani for everyone. The whole crew embraces the time they have for each other and tries to get themselves prepared for the mission ahead – landing on Mars.

Karuna blames Lambo for being irresponsible and decides to walk away from the mission. Laanya tries to convince him to stay on. When Karuna issues an ultimatum of choosing between him and Lambo, Laanya chooses the latter. Karuna leaves, heartbroken. Lambo convinces Laanya to take on the role of lead trainer. But Laanya is in for a rude shock - a terrible truth about Lambo’s mission awaits her.

The crew gets ready to take the bus to leave for the airport. Laanya is nervous about leading the crew towards a mission with a secret. She shares it with Samyuktha and they decide to handle the situation together. But things go awry when Nakulesh goes missing.

So, the crew think that they are on Mars. Laanya and Samyuktha try to manage their expectations and to keep them within the ‘space missile’. Meanwhile, Lambo is basking in the fame of his successful mission.

Guilt about cheating the world haunts Lambo and eventually catches up with him. He goes through a nervous breakdown. But the crew on ‘Mars’ are losing their minds about being trapped inside and start to rebel against Laanya. Will the truth finally be revealed?

Lambo needs to make a decision – is he going to hold on to the lies or finally find redemption by exposing himself? As the dust settles, everyone finds themselves in a position to make a choice whether to stay on or leave.
