Plot title: A Better Life Movie plot: A Better Life begins with Carlos Galindo (Demian Bichir) waking up and going to work. He works as part of a two-man crew with Blasco Martinez (Joaquin Cosio) as a gardener. Blasco is ready to return to Mexico and continually tries to persuade Carlos to purchase his business from him, which includes the work truck and professional gardening tools.Carlos' son Luis (Jose Julian) is in high school and is dating Ruthie Valdez, the niece of a prominent and powerful local gang leader. Although Ruthies influences get Luis into trouble, she sincerely loves and cares about him. Luis regularly goes to her house after school and is surrounded by gangs and the violence of the streets. This environment further has Luis contemplating his choice of submitting to the gang lifestyle. Luis and Carlos are at odds with each other because Luis is embarrassed by his father and, although he does not wish to follow in his footsteps, has a hard time committing himself to his education. However, his relationship with Ruthie pushes him more in the wrong direction, and his friend Facundo (Bobby Soto) wants to join the local gang and pressures Luis into doing the same.Carlos calls his sister Anna (Dolores Heredia) and asks her for financial assistance to purchase the gardening business from Blasco. Although she wishes to help him, she must first speak with her husband. The next evening, she shows up at his house with the $12,000 he asked for. She reveals to him that it is her daughters education fund.
