A scientist in the distant future has set out to avert a catastrophic
ecological disaster and sends a small number of
high tech devices that resemble toys
back in time to the 21st century. Ending up in
Seattle, they are discovered by siblings Noah Wilder and his younger sister Emma. The "toys" are initially incomprehensible to them, other than one which appears to be a
stuffed rabbit. The children keep their discovery a secret from their parents. Emma becomes telepathically connected to the rabbit, naming it "Mimzy", which imparts knowledge onto her. The children gain
genius-level
intellects and
psionic powers – Noah can
teleport objects using a card-sized rectangle of green lines of light and a conch shell to control spiders, but thanks to her link, Emma develops more advanced abilities, becoming the only one who can use the "spinners", stones that can float and produce a
force field. Emma describes herself as "the chosen one" but names Noah as "the engineer" without which she cannot "build the bridge to the future". The children's parents and Larry White, Noah's science teacher, discover the devices and the children's powers. By mistake, Noah causes a
power outage over half the state of Washington, alerting the
FBI to their activities. The family is held for questioning by Agent Nathaniel Broadman, during which Mimzy is revealed as
artificial life using
nanotechnology created by
Intel. Emma relates a dire message from Mimzy which states that many of her kind were sent into the past before, but none of them were able to return to their proper time period, because they lacked an "engineer" like Noah and now Mimzy, the last one that the scientist was able to send back, is beginning to deteriorate. To save the future, Mimzy must acquire a sample of uncorrupted human DNA to correct the damage done to DNA by ecological catastrophes. The FBI do not believe them, so Noah and Emma use their powers to escape. Mimzy absorbs a
tear from Emma, which contains her DNA. Via the time portal that Noah constructs using the toys, Mimzy returns to the future, leaving a
Sri Yantra symbol. Larry, who witnessed Mimzy being returned to the future, says he saw "numbers", a reference to a
dream he had that related to him winning lottery numbers he had missed out before by never buying a ticket. In the future, Mimzy provides the genetic information required to restore humanity, both physically and mentally, with Emma being dubbed "Our Mother" by the populace. ==Cast==
