When financial instability forces him to teach English to immigrants, a heartbroken, over-imaginative New Yorker must help a ragtag bunch of foreigners pass the class or risk losing what little he has left.

This logline attempt is better than the last one.

My one critique would be, “financial instability” is a situation.
But in a movie, you need a solid incident that shows financial instability.

An example would be:
The problem: The lead character’s landlord tells him he has 30 to pay his back rent or he will be kicked out of his apartment.
The Answer: Then he gets this offer. If he can teach the immigrants to speak English?he will receive enough money to pay the back rent.
The Catch: Everyone must pass the exam if the lead character is to get the ‘big bonus’ so if even one student fails the lead will lose his home.
The conflict: Almost all the immigrants don’t speak English… at all.

The B story: One of the few immigrants who does speak a little English is the love interest.? He must work with her if he is to teach the immigrants to speak English.
The B Conflict: He has a fiance who does not like immigrants.
