Part 1. Everything About Their Brother Lost In Space Movie Synopsis

Timothy Snyder came from the orphanage years ago and was adopted by the rich Snyder family. Since the day he stepped through the doors of the lavish mansion, he felt nothing but warmth and compassion. He felt that he was so lucky to be part of that harmonious family. Growing up, he had the full support of his loving three older sisters.

Gianna was the eldest among them, stern but responsible. She might look unapproachable, but her concern for Timothy was genuine. The middle one was Helena, who lost her sight since she was little. Even though she was blind, she was gentle and soft-spoken, always taking care of Timothy. Lastly, Arya, the boxing champ, promised to always protect him from harm.

Being surrounded by such amazing sisters was like a huge blessing for Timothy. In return, he wanted to be the best brother he could be. So, he studied hard at school, making sure that he would not disappoint them, especially Gianna. The love he earned from them was something he could not lose.

Yet that unbreakable belief was ruined when Matthew came, the self-acclaimed biological son of the Snyder family. He appeared kind and humble, but beneath his delightful smiles was a rotten core hiding. They had no idea that he falsified the documents just to make them believe that he was the real heir.

Time passed, and Matthew slowly poisoned their minds. With his deadly lies fueled by his inner insecurity, he started to tarnish Timothy’s pristine image. It started with one accusation until it became many staged incidents, like accusing Timothy of pushing him down the stairs. From then on, Gianna and her sister no longer saw Timothy as their brother.

All his hard work and achievements were ignored. What they could only see was the goodness that Matthew gave. Timothy was cast out and felt that he was no longer needed in the family that once warmly welcomed him. It was then that he decided to be a volunteer for the Hail Mary Project, a one-way mission to Planet Artemis.

Would his sisters realise his worth before it’s too late? Watch the much-awaited ending of this sci-fi drama entitled Their Brother Lost In Space exclusively on ReelShort!

Part 2. Introducing Their Brother Lost In Space Main Characters

2.1 Who Is Timothy Snyder?

Timothy Snyder was the selfless male protagonist of this short drama. He was known as the adopted son of the influential Snyder family, but was found out to be the real one in the end. Intelligent and kind, he carried the rare Pilgrim gene fit for the Hail Mary mission in space. Unloved by his family, he saved humanity without asking anything in return.

You probably saw him in some romantic ReelShort series last year. But in 2026, Luke Dodge came out with an extraordinary role as Timothy. He was born on July 25, 2005, in Los Angeles. From being a commercial model, he turned into a talented vertical short actor. Watch this handsome lad on: The Tutor Trap, Taming My Bullies, and Tell Me Not to Love You.

2.2 Who Is Gianna Snyder?

Gianna Snyder was the eldest sister of Timothy. She posed a tough exterior, always making sure that things were perfect according to her plans. Authoritative and disciplined, she was only concern of his welfare. Yet when Matthew poisoned her mind, she neglected him. The greatest burden she had was the remorse of judging her own brother quickly.

Here was the captivating film actress from Fort Worth, Texas, Lindy Jones. When she pursued acting, she moved to Los Angeles. She was part of a theatre production and some indie film projects. You can see more of her in these ReelShort flicks: My Father, My Hero, and Beg for My Return After Kicking Me Out.

Part 3. What Happened In Their Brother Lost In Space Staggering Episodes?

3.1 The Pilgrim Gene Discovery

Don’t miss the pilot episode of Their Brother Lost In Space. It showed the secret decision that made a huge difference in Timothy’s life. After a thorough test and research, NASX found out that he carried a rare gene called Pilgrim. It only meant that he was the only key to save the entire planet from destruction.  

What made this episode unforgettable was the mixture of science and drama, perfectly blended together. Timothy’s character deeply showed the hurt and pain he suffered from his ungrateful family. Although it was a truly devastating choice, he realised that it would benefit not only the Snyders but also humanity.

3.2 Before Leaving The Earth

In this episode, the stakes went even higher. Timothy was given a total of 72 hours to get ready. Yet he never told his family about his one-way mission to Planet Artemis. He only left some memorabilia that would eventually make sense upon his departure. Within the time frame given, he completed the cybernetic eye that he made for Helena.

From painful accusations, he chose to stay silent and stay focused on his plan. Her sisters had no idea that he graduated at the top of his class. Even the chronic asthma that he had from the fire incident was beyond their understanding. All they knew was that Matthew was the victim. The launch drew closer, but they were still blinded by the lies.

3.3 The Epic Ending

Last but not least, the reckoning that vanquished the hearts of the three sisters. Matthew was proven to be a fraud and was exiled to a mental facility. From the moment that the truth came out, the entire Snyder family were sorry for what they did. However, it was far too late to make Timothy feel that he was longed for.

Thirty years had passed, and Timothy finally landed on Planet Artemis. Accompanied by his robotic friend, he felt the peace that he never had before. His sisters, now old and wrinkled, were hoping for his happiness. Time became a divider between them. Timothy was still young and strong, ready to start his new journey.

Part 4. What Can We Learn From Timothy Snyder and Gianna Snyder?

4.1 Give The Benefit Of The Doubt   

One of the greatest lessons that we could get from Their Brother Lost In Space was the importance of trust. In the story, Gianna rushed into conclusion without knowing the truth. She did not listen nor dare to understand Timothy’s situation. She failed to ask him and evaluate what was true and not.

Whether in families and friendships, we can’t just accuse someone of something that they are not. We often hear half of the story, which is not enough for us to conclude. It is better to always seek understanding and stop putting hate over calmness. We can build stronger relationships if we learn to give others the benefit of the doubt.

4.2 Love Freely Before It’s Too Late

Another wonderful message that this ReelShort drama left us was about loving people freely. Gianna and the Snyder family suffered a lifelong regret. They chose to ignore his efforts. Until they learn about the truth, they cannot do anything. Timothy was already out of their reach, too far away for them to embrace.

Unlike them, Timothy chose to be kind and love them unconditionally. He expressed his care for them in silence. With his actions, he ensured that he still made them valued because they truly mattered to him. In reality, we should always remember that life is unpredictable. The right time is now to make your loved ones feel loved and cherished.
