$5 a Day (2008)

In L.A., Flynn Parker loses his health-inspector job when his time in prison comes to light, his girlfriend Maggie moves out because of his prevarications, and his ne'er-do-well father Nat summons him to Atlantic City with a malignant-cancer tale. Flynn doesn't like Nat, a small-time hustler--and the cause of Flynn's jail time--but Nat cajoles his son into a cross-country trip through family memories toward New Mexico, where an experimental treatment awaits. The trip is not just about the past, but about whether either can tell the truth--then what to do with those truths. From time to time, Flynn calls Maggie to leave messages. And what about Flynn's mother?
