Bizarre things start happening in the little New Mexico town where UFOs were spotted in 1947. Cut to 1999, when a cute high-school student saves the life of a teenage waitress. Surrounded by cliques of clever, angst-filled classmates, the two form a bond that threatens the survival of a secret universe involving superhuman powers, a yen for hot sauce and an alien gene pool.

After reluctantly returning to her tourist-trap hometown of Roswell, New Mexico, the daughter of undocumented immigrants discovers a shocking truth about her teenage crush who is now a police officer—he’s an alien who has kept his unearthly abilities hidden his entire life. She protects his secret as the two reconnect and begin to investigate his origins, but when a violent attack and long-standing government cover-up point to a greater alien presence on Earth, the politics of fear and hatred threaten to expose him and destroy their deepening romance.
