They were enemies on the cricket grounds before war breaks out but now they face a common enemy in Malaya. They have to defend a bridge that would prevent the Japanese army reaching Singapore. An impossible task that creates the first heroes and martyrs of the Pacific War.

Anwardi, nice work. Let's break this down from 48 words to 30ish. We need The Big Three – the hero, goal, and problem of your story and genre.

Two rivals on the cricket field are conscripted to fight in the Pacific War where they must defend a bridge to prevent the Japanese army from reaching Singapore.

I'm not saying this is the one to use but it's the same as yours just in 28 words and it doesn't give away the ending. The stakes are good and the genre is clear. It's just my quick thoughts so keep working on it. I hope you get it made, I'll go watch it!

I think it's an interesting premise, but the logline is too long. How about:

'Two cricket foes, one Australian, one Indian, face a common enemy in Malaya during WWII, when they must defend a bridge against the Japanese army reaching Singapore.'

When at the start of the Pacific offensive of World War II Japan launches their ground troop invasion of Singapore, former fierce cricket rivals must rally together and make a stand against superior forces to hold the last bridge to Singapore.

Was thinking that the phrase first martyrs should be 'amongst the first martyrs of the Pacific War as this incident occurred about three weeks after Pearl Harbor.

Forget the Naysayers Anwardi. It's a longish logline but it creates a powerful setup. Work out how to cut words out without losing meaning, eg

Enemies on the cricket pitches before the war, they now face a common enemy. They defend a bridge preventing the Japanese reaching Singapore. An impossible task. They are first martyrs of the Pacific War.

The story is based around this event. http://en.wikipedia.org/wiki/Parit_Sulong_Massacre

Noted but Singapore doesn't come much into play as the story starts in Sydney where the protagonist was from. The other guy was from Delhi. The bridge is 100km north of Singapore - the last bridge standing before the Causeway to Singapore.

My problem is "they" doesn't really work as a protagonist, and an audience member can't identify with a group of people simultaneously. You need to give us a single protagonist with whom the audience can empathise.

Also - can you make the link between your protagonist and Singapore more personal? For instance, the protagonist's family or lover etc. live in Singapore?

Well, it sounds interesting, I like the premise.

Based on true incident on the bridge of Parit Sulong in Malaya. Hundreds of Australians and Indians died whilst defending the bridge. The two main characters are fictional - an Australian batsmen and and Indian fast bowler.

Is this based on a true story?
