After finding his new love, Mark is headed on his honeymoon to Rio de Janeiro, Brazil…who could ask for more? His plans are sidelined when he is called upon by the DEA to revisit a small Colombian Amazon River border town on a dangerous mission to intercept from the local drug ring an outdated secret Russian encryption device. His new bride is clueless as to the purpose of the hot, humid jungle diversion. Meeting with a local jungle guide and potentially compromised undercover DEA agent named Louie, the trio set out to foil the plans of the cartel while trying to formulate a dangerous double-cross as they go. In the end it's the local children that help them discover a plot more sinister than the mere unrestricted flow of illegal drugs crossing "Las Tres Fronteras," the narrow Amazon River border crossing between Brazil, Colombia and Peru.
