Tides (film)

After a global catastrophe nearly wipes out humanity on Earth, Earth's elites flee to a Kepler-209 space colony. A young astronaut named Blake from the Kepler colony returns to Earth with fellow astronauts Tucker and Holden. Their mission is to test whether Earth is suitable for human habitation and reproduction. Kepler-209 residents have modern technology and space travel but they have become infertile from heavy radiation there. This is the second attempt to return to Earth.

The space capsule lands roughly on a tidal flat near the Henderson Hub, a weather beacon that broadcasts telemetry data back to Kepler-209. Holden is killed, while Tucker commits suicide after a group of fertile humans, nicknamed "The Muds", fatally wounds him and captures him and Blake, and removes technology from the shuttle. Blake is imprisoned by the Muds and nearly drowns, but she is saved by a girl named Maila.

The Muds are invaded by a hostile group that kidnaps many of them. They are taken to a cargo ship that rises above the frequent floods and storms. The aggressors are led by a former Kepler-209 resident named Gibson, who is a survivor from a previous Earth mission led by Blake's father, once thought to have no survivors as its capsule was destroyed along with its communication equipment.

Blake realizes she is fertile, and she meets the children of the Muds, whom Gibson is educating. Gibson claims the Muds killed Blake's father, but Blake learns that he has been locked away because he sided with the Muds, believing that Kepler residents should never return to Earth. Gibson introduces Blake to his adoptive son and his partner - she claims that he saved her and her son from certain death. Despite the total loss of the first mission's capsule and the communication system of the second being destroyed, Blake realizes she can instead use the weather beacon to transmit her fertility data back to Kepler with the biometer as proof of survival and fertility of Keplers while on a now recovering and viable Earth. However, Blake soon discovers the girls are being held captive for Gibson's future breeding plans with male Keplers upon their full return to the planet. She sides with the Muds, attacks the guards, and releases the girls and their families.

After freeing the Muds, she goes to free her father. They notice Gibson moving toward the Henderson Hub. Blake discovers that Gibson's adoptive son Neil is actually her half-brother (after her father impregnated Neil's mother). As Neil is technically fertile due to his mother being a Mud and also biologically a Kepler, Gibson is able to use the biometer to collect his fertility data to signal back to Kepler. She tries to stop the data upload from being broadcast back to Kepler-209, but Gibson is able to transmit the data. Blake strangles and drowns Gibson, almost drowning herself, but Maila's mother rescues her and revives her. Blake and her father rejoin the Muds and Neil and they set out in a tugboat. A closing scene shows the Mud children hidden from the prior Kepler raiders fearfully watching an approach of figures through the fog, which turn out to be their kidnapped parents returning safely home.^[4]
